1# Updating Information for DragonFly users. 2# 3# 4# This file should warn you of any pitfalls which you might need to work around 5# when trying to update your DragonFly system. The information below is 6# in reverse-time order, with the latest information at the top. 7# 8# If you discover any problem, please contact the bugs@lists.dragonflybsd.org 9# mailing list with the details. 10 11+-----------------------------------------------------------------------+ 12+ UPGRADING DRAGONFLY FROM 5.4 TO LATER VERSIONS + 13+-----------------------------------------------------------------------+ 14 15FFS_ROOT OPTION REMOVED 16----------------------- 17 18The FFS_ROOT kernel configuration option has been finally removed, after 19having been a no-op since 4.9. That means users using a custom kernel 20configuration file that still contains it need to remove the option from 21that file. 22 23+-----------------------------------------------------------------------+ 24+ UPGRADING DRAGONFLY FROM 5.2 TO LATER VERSIONS + 25+-----------------------------------------------------------------------+ 26 27DIGI, RP AND SI DRIVERS REMOVED 28------------------------------- 29 30The digi(4), rp(4) and si(4) serial drivers have been removed. None of 31them were in our default kernel configuration file. The sicontrol(8) 32utility was removed, too. 33 34MKINITRD COMMAND REMOVED 35------------------------ 36 37The mkinitrd(8) command is removed and its functionality is replaced by 38the new "initrd" make target. After rebooting into the new world and 39verifying everything works, execute "make initrd" to upgrade the rescue 40tools and initrd image. 41 42IPSEC, IPSEC_ESP AND IPSEC_DEBUG REMOVED FROM VKERNEL64 CONFIG 43-------------------------------------------------------------- 44 45IPsec has been removed from the system. Of our standard kernel 46configurations, only the virtual kernel one had it. People running 47vkernels with configuration files derived from our VKERNEL64 will 48have to remove these options manually. 49 50+-----------------------------------------------------------------------+ 51+ UPGRADING DRAGONFLY FROM 5.0 TO LATER VERSIONS + 52+-----------------------------------------------------------------------+ 53 54VIRTIO_PCI REMOVED FROM KERNEL CONFIG 55------------------------------------- 56 57The "device virtio_pci" line in X86_64_GENERIC has been removed. People 58with configuration files derived from it have to remove it manually. 59 60VARIOUS 'R' COMMANDS AND DAEMONS REMOVED 61---------------------------------------- 62 63rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed. 64For those that still need them, there is the net/bsdrcmds port. 65 66VARIOUS FORMER OPTIONS REMOVED 67------------------------------ 68 69Various former kernel configuration options which had been no-ops for 70some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B, 71_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in 72their kernel configuration files have to remove them. 73 74BOOTSTRAPPING LIMITED FROM PRE 4.4 75---------------------------------- 76 77Upgrading to 5.1 and later versions now require at least 4.4 in 78preparations for upcoming base compilers updates. 79 80IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED 81------------------------------------------ 82 83if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had 84already been removed from our default kernel configuration before 5.0, 85so only people with custom configurations based on earlier X86_64_GENERIC 86will have to remove it manually. 87 88The faith(4) interface has been completely removed after it had also 89been removed from our default kernel configuration. 90 91+-----------------------------------------------------------------------+ 92+ UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS + 93+-----------------------------------------------------------------------+ 94 95FFS_ROOT OPTION DISABLED 96------------------------ 97 98The FFS_ROOT option has been made a no-op and will be completely removed 99at some point in the future. Users with a custom kernel configuration 100can remove this option from it now. 101 102+-----------------------------------------------------------------------+ 103+ UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS + 104+-----------------------------------------------------------------------+ 105 106DSA OPENSSH KEYS DEPRECATED 107--------------------------- 108 109Note that DSA OpenSSH keys were deprecated in the 4.6 to 4.8 release. 110If you are upgrading from a release older than 4.8 and use DSA OpenSSH 111keys, please update your private/public key pair or risk locking 112yourself out. 113 114AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 115----------------------------------------------- 116 117They were all in our X86_64_GENERIC kernel configuration file, along with 118the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 119configuration files derived from it need adjustment. 120 121PORTAL FILE SYSTEM REMOVED 122-------------------------- 123 124It has been broken for a long time now. 125 126BINUTILS 2.27 REPLACES 2.24, PRIMARY 127------------------------------------ 128 129The oldest of the two versions of Binutils, version 2.24, was removed 130and replaced with Binutils 2.27. It becomes the primary version version 131of binutils and version 2.25 becomes the alternate. 132 133The accepted values of BINUTILSVER are now "binutils227" (default) and 134"binutils225". The building of Binutils 2.25 can be prevented by setting 135NO_ALTBINUTILS=yes in make.conf. 136 137COMPAT_43 KERNEL OPTION REMOVED 138------------------------------- 139 140It was commented out in our default configs for several years now, but 141might still be present in custom configs created before Nov. 2011. 142 143OPENSSL REMOVED 144--------------- 145 146OpenSSL has been removed from base and replaced with a private version of 147LibreSSL. The previously installed OpenSSL libraries, headers, and man 148pages will remain on the system unless the "make upgrade" command is 149specifically instructed to remove them. To do this, define 150REMOVE_OPENSSL_FILES for the upgrade command, e.g. 151"make upgrade REMOVE_OPENSSL_FILES=yes" 152 15328-Oct-2016: openssl has been replaced by ressl. It is recommended that any 154stale OpenSSL files be removed to avoid configuration scripts from using 155the stale and potentially vulnerable version, but all binaries that are 156dynamically linked to the OpenSSL libraries should be rebuilt first to 157avoid breakage. 158 159OPENSSH HPN REMOVED 160------------------- 161 162It has become too cumbersome to maintain HPN patches in OpenSSH in base. 163To use OpenSSH in base remove HPN config, if you have added it. 164Check files below for HPN config, see a few lines below. 165 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 166sshd(8) will fail to start if HPN config is used. 167 168NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 169 170HPN config: 171HPNDisabled 172HPNBufferSize 173TcpRcvBuf 174TcpRcvBufPoll 175NoneEnabled 176NoneSwitch 177cipher MTR-AES-CTR 178cipher NONE 179 180OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 181circumstances, especially for networking. 182If HPN functionality is needed, install security/openssh from dports. 183 184CS, EX AND VX DRIVERS REMOVED 185----------------------------- 186 187The cs(4), ex(4) and vx(4) drivers have been removed. They were very 188old and its doubtful they ever worked properly in x86_64 but they were 189in X86_64_GENERIC, so custom configurations derived from it have to be 190adjusted. 191 192+-----------------------------------------------------------------------+ 193+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 194+-----------------------------------------------------------------------+ 195 196AMD REMOVED 197----------- 198 199The am-utils automounter suite has been removed. It stopped working 200at some point and was never fixed. autofs(5) and the associated 201userland has been brought in from FreeBSD and replaces it. 202 203AN DRIVER REMOVED 204----------------- 205 206The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 207config file, so any configurations derived from it have to be adjusted. 208 209/DEV/DRI GROUP CHANGED 210---------------------- 211 212The default group assigned to /dev/dri entries has been changed 213from 'wheel' to 'video' with the id of '44'. If you want to have 214access to the dri devices please add yourself to the video group 215with: 216 217# pw groupmod video -m $USER 218 219+-----------------------------------------------------------------------+ 220+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 221+-----------------------------------------------------------------------+ 222 223DSCHED REMOVED 224-------------- 225 226dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 227in our default kernel config file. So the DSCHED_FQ option has been turned 228into a no-op for now and can be removed from custom configurations. 229 230EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 231------------------------------------------------- 232 233The est(4) driver has been removed. All CPUs it supported (except one) 234were 32 bits only. Those who are still using the Core 2 Duo T7500 should 235report back if there are any issues with this CPU and our regular ACPI 236P-state support. 237 238Also, compile_et(1) and com_err(3) have been removed as well. They 239should have been removed along with kerberos support, back in 2009. 240 241SEVERAL LOCALES RENAMED 242----------------------- 243 244Several locales were using obsolete and misleading names, and thus have 245been adjusted to current standards. Any users of the following locales 246need to select alternates: 247 248DFLY 4.2 locale DFLY 4.4 alterative locale 249--------------- ------------------------------------ 250mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 251no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 252no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 253no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 254sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 255sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 256sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 257zh_CN.GBK zh_Hans_CN.GBK 258zh_CN.UTF-8 zh_Hans_CN.UTF-8 259zh_CN.eucCN zh_Hans_CN.eucCN 260zh_CN.GB2312 zh_Hans_CH.GB2312 261zh_CN.GB18030 zh_Hans_CH.GB18030 262zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 263zh_HK.UTF_8 zh_Hant_HK.UTF-8 264zh_TW.Big5 zh_Hant_TW.Big5 265zh_TW.UTF-8 zh_Hant_TW.UTF-8 266 267+-----------------------------------------------------------------------+ 268+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 269+-----------------------------------------------------------------------+ 270 271BINUTILS 2.25 REPLACES 2.22, PRIMARY 272------------------------------------ 273 274The oldest of the two versions of Binutils, version 2.22, was removed 275and replaced with Binutils 2.25. It becomes the primary version version 276of binutils and version 2.24 becomes the alternate. There are 8 current 277CVE written against 2.24, so for security reasons version 2.25 should 278always be used. 279 280The accepted values of BINUTILSVER are now "binutils225" (default) and 281"binutils224". The building of Binutils 2.24 can be prevented by setting 282NO_ALTBINUTILS=yes in make.conf. 283 284LOADER OPTIONS CHANGED 285---------------------- 286 287Right after the development branch started, the Fred art accompanying the 288loader menu was improved. The line between Fred and the menu was removed 289by default (but can optionally be returned) and the placement shifted as 290a result. The drawing was improved, and the colored version was improved, 291changing the eyes and wing color from white to red. A new color version 292of Fred was added, one with a blue scheme. 293 294The loader menu defaults have changed since release 4.0: The vertical 295line was removed, the loader is displayed in color by default*, and the 296blue scheme is used. 297 298The loader.conf changes are: 299loader_color: option has been removed 300loader_plain: option has been added, it changed menu to monochrome 301fred_is_red: changes color scheme from blue to red 302fred_is_blue: option existed only on 4.1, it has been removed 303fred_separated: Adds line between Fred and menu (as seen previously) 304 305* If loader.conf defines "console" as "comconsole" or "console" is defined 306 in the environment as "comconsole" then color will not be displayed, 307 even if loader_plain value is "NO". 308 309SENDMAIL REMOVED FROM BASE 310-------------------------- 311 312The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 313If the system being upgraded is still configured to use the sendmail 314binaries from base, the "make upgrade" command will fail. 315 316The administrator must change /etc/mail/mailer.conf to switch the 317mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 318command that permanently removes sendmail executables and could 319potentially break a running mail server. 320 321Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 322detailed instructions on how to configure the MTA selection. 323 324_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 325-------------------------------------------- 326 327The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 328no-ops. They can be removed from custom kernel configurations. 329 330SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 331-------------------------------------------- 332 333Many more sound devices may be detected. 334 335If the default device choosen isn't to your liking, setting the sysctl 336hw.snd.default_unit to a different number will change it. 337 338SCTP SUPPORT DROPPED 339-------------------- 340 341Support for the SCTP protocol has been removed. 342 343OLD USB DRIVERS REMOVED 344----------------------- 345 346The old USB stack, along with the kernel config option "device oldusb" 347and the make.conf variable "WANT_OLDUSB" have been removed. This means 348that for custom kernel configuration files which were derived from a 349GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 350various (old USB stack specific) devices will now complain about being 351unknown: 352 353 * oldusb (obviously) 354 * natausb (not yet ported to usb4bsd) 355 * rue (not yet ported to usb4bsd) 356 * ugen (no longer needed in usb4bsd) 357 * urio (not yet ported to usb4bsd) 358 * uscanner (no longer needed in usb4bsd) 359 360They should be removed or commented out in such custom kernel configs. 361 362GCC 5 363----- 364 365The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 366The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 367NO_CXX. The latter was never documented and the latest versions of GCC are 368partially written in C++ so a C++ compiler is no longer optional. In 369practical terms it has not been optional for many years as other base 370components are also written in C++. The resource savings by avoiding 371building Objective-C compiler is so small, the complexity added by NO_OBJC 372internally was deemed a bad tradeoff so that is the reason for its removal. 373Also note that no "info" pages are installed with GCC 5. After this entry 374was originally written, all info pages were removed from DragonFly. 375 376GCC 5.1 has been designated as the primary compiler. As such, there is a 377new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 378the designated secondary compiler, GCC 4.7. However, while DPorts 379primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 380if building ports from source is desired, don't block building of the 381secondary compiler. 382 383+-----------------------------------------------------------------------+ 384+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 385+-----------------------------------------------------------------------+ 386 387SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 388------------------------------------------- 389 390DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 391the default now (even on single-core systems), both for, like, 21 months. 392We kept the options around as no-ops as a convenience, to allow people 393using the same config for the then current release and the then current 394master. That period is now over, so any configs still having those 395options have to be adjusted. 396 397SYSVIPC SYSCALLS MADE NON-OPTIONAL 398---------------------------------- 399 400The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 401now compiled in by default. The options are no-ops for now. 402 403DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 404-------------------------------------------------------------------- 405 406The default driver for those controllers is now mrsas(4) due to reports 407of file system corruption using the mfi(4) driver. The whole issue (and 408how to deal with potential problems when switching) was explained here: 409 410http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 411 412A tunable is provided for letting those controllers still attach via 413the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 414 415OLDER NETWORK DRIVERS MOVED TO I386 ONLY 416---------------------------------------- 417 418The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 419and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 420removed in kernel configs derived from X86_64_GENERIC. 421 422+-----------------------------------------------------------------------+ 423+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 424+-----------------------------------------------------------------------+ 425 426UPDATE FROM MOST RECENT 3.6 427--------------------------- 428 429Versions of 3.6 built before June 25th have a bug where installworld might 430crash during installation of the new initrd. Upgrade to the latest version 431of 3.6 before updating to 3.8 or later. 432 433ATM, IPX, NCP AND NWFS SUPPORT DROPPED 434-------------------------------------- 435 436Support for the IPX and NCP network protocols and for mouting NetWare 437file systems has been dropped. Dito for ATM protocol support. 438 439INITRD IMAGES NOW INSTALLED BY DEFAULT 440-------------------------------------- 441 442An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 443 444Older images installed under the file name of initrd.img will be removed 445automatically by the make upgrade process. 446 447USB4BSD IS NOW THE DEFAULT USB STACK 448------------------------------------ 449 450To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 451replace "device usb" with "device oldusb" in the kernel configuration. 452 453MORE ISA SUPPORT DROPPED 454------------------------ 455 456ISA support has been dropped from the following drivers: adv(4), an(4), 457ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 458si(4), sn(4), and stg(4). 459 460+-----------------------------------------------------------------------+ 461+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 462+-----------------------------------------------------------------------+ 463 464ABI CHANGE 465---------- 466 467Installed third-party software (dports) will have to be rebuilt after upgrade, 468or reinstalled from binary packages. 469 470UPDATING FROM 3.4 TO 3.6 471------------------------ 472 473This only applies for this specific upgrade due to locale changes; it is 474not needed for upgrades after 3.6. Please update in this order: 475 476make buildworld 477make buildkernel 478make installworld 479make installkernel 480*reboot* 481make upgrade 482 483See this mailing list post for details: 484http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 485 486CYRIX OPTIONS REMOVED 487--------------------- 488 489The following Cyrix related options have been removed: CPU_BTB_EN, 490CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 491CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 492CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 493 494ISA SUPPORT REMOVED FROM RP(4) 495------------------------------ 496 497ISA support has been removed from the rp(4) driver. It is now PCI only. 498 499+-----------------------------------------------------------------------+ 500+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 501+-----------------------------------------------------------------------+ 502 503COMPAT_SUNOS OPTION REMOVED 504--------------------------- 505 506The COMPAT_SUNOS option has been removed. It was meant to provide binary 507compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 508 509ISA SOUND CARD SUPPORT REMOVED 510------------------------------ 511 512The following modules have been removed (all for ISA sound cards): 513snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 514 515GCC 4.7 516------- 517 518DragonFly has switched base compilers. GCC 4.7 is now the default 519compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 520variable ceases to work now. 521 522Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 523/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 524highly discouraged. There are a few packages in pkgsrc that do not build 525with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 526this time, it is recommended to keep both compilers on the base system. 527 528SMP OPTION REMOVED 529------------------ 530 531The SMP kernel option has been made a no-op. All kernels now feature SMP 532support. If you have 'options SMP' in your kernel config, you can as well 533remove it. 534 535DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 536--------------------------------------------------------------------------- 537 538The DEVICE_POLLING kernel option has been made a no-op and it has been 539replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 540kernel config, you need to change it to IFPOLL_ENABLE. 541 542Also, the KTR_POLLING kernel option has been removed, so it must be 543removed from kernel configs that have it. 544 545BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 546--------------------------------------------------- 547 548The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 549cards will no longer be detected. 550 551The same has been done for Stallion multiport serial controllers. stli(4) 552has been completely removed (along with the stlload(8) and stlstty(8) 553utilities) and stl(4) was changed to support only PCI cards. Similarly, 554ISA support was removed from cy(4) too. All these drivers are i386 only. 555 556COMPAT_OLDISA OPTION GONE 557------------------------- 558 559The i386 specific COMPAT_OLDISA kernel option has been removed, since 560nothing needs it anymore. 561 562+-----------------------------------------------------------------------+ 563+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 564+-----------------------------------------------------------------------+ 565 566APIC_IO OPTION REMOVED 567---------------------- 568 569The APIC_IO kernel option is no longer accepted after having been without 570effect for a while. The hw.ioapic_enable tunable now serves its purpose. 571If you have 'options APIC_IO' in your kernel config, you'll have to 572remove it. 573 574WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 575----------------------------------------- 576 577The wdog framework is now compiled into our kernels by default, so the 578options are no longer needed. 579 580DOSCMD(1) REMOVED 581----------------- 582 583doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 584NO_X make.conf option was removed too. 585 586GCC 4.7 587------- 588 589GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 590default compiler in base (default is still GCC 4.4). 591 592Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 593NO_GCC47 in /etc/make.conf. 594 595USB4BSD 596------- 597 598A new USB stack (from FreeBSD) has been brought in. The following 599modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 600usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 601and uaudio. 602 603It is not yet the default. To activate it, WANT_USB4BSD=yes has to 604be put in make.conf and device "usb4bsd" (quotes needed) has to 605replace device usb in the kernel config. After that, a full 606build/install/upgrade cycle is needed. 607 608Note that this is experimental and incomplete, but we are interested 609in hearing about issues with it, of course. 610 611ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 612--------------------------------------------- 613 614ISA adapter support was dropped from the aic(4) driver. 615 616+-----------------------------------------------------------------------+ 617+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 618+-----------------------------------------------------------------------+ 619 620SEVERAL ISA DRIVERS REMOVED 621--------------------------- 622 623The following ISA only drivers have been removed along with a couple of 624associated userland tools: 625 626aha(4) 627asc(4) & sasc(1) 628ctx 629dgb(4) 630el(4) 631gpib 632gsc(4) & sgsc(1) 633ie(4) 634labpc(4) 635le(4) 636mse(4) 637rc(4) 638rdp(4) 639spigot 640tw(4) & xten(1) & xtend(8) 641wl(4) & wlconfig(8) 642wt(4) 643 644Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 645config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 646file. 647 648If buildkernel complains about any of these drivers, just remove them 649from your kernel configuration. 650 651BINUTILS 2.20 652------------- 653Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 654values of BINUTILSVERS are now binutils221 and binutils222 (default). 655 656BUILDWORLD/-KERNEL PARALLELIZATION WORK 657--------------------------------------- 658Due to changes in the way we build with more than one make job, you 659will have to update install(1) and mkdir(1) prior to buildworld if you 660want to build with 'make -j': 661 662cd /usr/src/usr.bin/xinstall; make; make install; make clean 663cd /usr/src/bin/mkdir; make; make install; make clean 664 665DMA(8) UPGRADE 666-------------- 667dma(8) has been upgraded to v0.7 which no longer supports the 668/etc/dma/virtusertable. Some of its functionality has been replaced 669with the MASQUERADE keyword and the EMAIL environment variable (see 670the dma(8) manual page). 671 672+-----------------------------------------------------------------------+ 673+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 674+-----------------------------------------------------------------------+ 675 676GCC 4.4 & BINUTILS 2.21 677----------------------- 678 679GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 680been made DragonFly's default Binutils. 681 682That means that any settings that set CCVER to 'gcc44' are not needed 683anymore. Instead, CCVER can be set to 'gcc41' to go back to using 684GCC 4.1. 685 686It also means that 'binutils221' as a value for BINUTILSVER has no 687effect anymore. 2.17 has been removed and 'binutils220' is available 688as an option. 689 690The NO_GCC44 option has been removed and will not affect the build 691anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 692building in a similar fashion. 693 694Note that you must do a full buildworld/buildkernel for upgrading. 695 696pkg_radd settings 697----------------- 698 699The config file for pkg_radd has moved from /etc/settings.conf to 700/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 701if this is needed. This warning only applies if /etc/settings.conf 702exists. pkg_radd will continue to work with defaults. 703 704+-----------------------------------------------------------------------+ 705+ 20100927 + 706+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 707+-----------------------------------------------------------------------+ 708 709OpenSSL 710-------- 711 712OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 713This shouldn't break any 3rd-party software, but you'll need to recompile your 7143rd-party software if you want it to link against the new version of OpenSSL. 715 716Loader 717------- 718 719A new loader (dloader) has been added which better handles booting from 720multiple kernel/module versions. 721 722To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 723 724 cd /usr/src 725 make buildworld 726 make installworld 727 make upgrade 728 make buildkernel KERNCONF=<KERNELNAME> 729 make installkernel KERNCONF=<KERNELNAME> 730 731Note that you must installworld and run the 'upgrade' target before 732installing the new kernel. 733 734BIND 735----- 736 737BIND has been removed from the base system. The ldns and drill tools have 738been added for basic functionality. Use 'drill' where you would normally 739use nslookup or dig, or install BIND from pkgsrc. It's available as 740net/bind95, net/bind96, or net/bind97 as of this writing. 741 742This only affects older systems upgrading to 2.8. New 2.8+ installs 743include BIND as a pkgsrc package. 744 745+-----------------------------------------------------------------------+ 746+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 747+ GENERAL + 748+-----------------------------------------------------------------------+ 749 750Instructions on how to obtain and maintain DragonFly source code using git 751are in the development(7) manual page. 752 753To upgrade a DragonFly system from sources you run the following sequence: 754 755 cd /usr/src 756 make buildworld 757 make buildkernel KERNCONF=<KERNELNAME> 758 make installkernel KERNCONF=<KERNELNAME> 759 make installworld 760 761You will also want to run the 'upgrade' target to upgrade your /etc and the 762rest of your system. The upgrade target is aware of stale files created by 763older DragonFly installations and should delete them automatically. 764 765 make upgrade 766 767See the build(7) manual page for further information. 768 769Once you've done a full build of the world and kernel you can do incremental 770upgrades of either by using the 'quickworld' and 'quickkernel' targets 771instead of 'buildworld' and 'buildkernel'. If you have any problems with 772the quick targets, try updating your repo first, and then a full buildworld 773and buildkernel as shown above, before asking for help. 774 775+-----------------------------------------------------------------------+ 776+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 777+-----------------------------------------------------------------------+ 778 779In 2.1 kernel and modules has moved to boot directory. For most cases 780this is handled automatically by 'make upgrade'. A few cases needs manual 781intervention: 782 783 * When installing a kernel without first doing a make buildworld, 784 installworld and upgrade to the same DESTDIR as kernel: 785 make DESTDIR/boot directory and move kernel and modules into this boot 786 directory; also move kernel.old and modules.old. 787 Typical example is vkernel(7), use (no modules used): 788 789 cd /var/vkernel 790 mkdir boot 791 chflags noschg kernel 792 mv kernel kernel.old boot 793 chflags schg boot/kernel 794 795 * When using a boot-only partition, /boot/loader.rc needs to be edited: 796 delete occurrences of '/boot/'. 797 These occurences can normally be deleted in any case, see loader(8). 798 799+-----------------------------------------------------------------------+ 800+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 801+-----------------------------------------------------------------------+ 802 803In 1.9 major changes to the disk management infrastructure have taken 804place. make upgrade may not catch all of your disk devices in /dev, 805so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 806are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 807and MAKEDEV no longer exists. 808 809The biggest changes in 1.9 are: 810 811(1) That whole-slice devices such as da0s1 no longer share the same device 812 id as partition c devices such as da0s1c. 813 814(2) The whole-disk device (e.g. da0) is full raw access to the disk, 815 with no snooping or reserved sectors. Consequently you cannot run 816 disklabel on this device. Instead you must run disklabel on a 817 whole-slice device. 818 819(3) The 'compatibility' partitions now use slice 0 in the device name, 820 so instead of da0a you must specify da0s0a. Also, as per (1) above, 821 accessing the disklabel for the compatibility partitions must be 822 done via slice 0 (da0s0). 823 824(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 825 and CCD now run through the disk management layer and are assigned 826 real disk management devices. VN and CCD in particular do not usually 827 use a MBR and disklabels must be accessed through the compatibility 828 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 829 don't name it 'ccd0s0' in the config file. 830 831Generally speaking, you have to get used to running fdisk and disklabel on 832the correctly specified device names. A lot of the wiggle, such as running 833disklabel on a partition, has been removed. 834 835+-----------------------------------------------------------------------+ 836+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 837+-----------------------------------------------------------------------+ 838 839> Kerberos IV 840------------- 841 842Kerberos IV (eBones) was removed from the tree, please consider moving to 843Kerberos 5 (Heimdal). 844 845> Package Management System 846--------------------------- 847 848Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 849management system. The necessary tools to build and maintain packages 850are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 851directories are in your PATH variable. 852 853In order to obtain a reasonably current snapshot of the pkgsrc tree, use 854the tarball from NetBSD: 855 856 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 857 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 858 859This tree can then be kept up to date with cvs update: 860 861 cd /usr/pkgsrc; cvs up 862 863NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 864build and install the pkgsrc bootstrap manually: 865 866 cd /usr/pkgsrc/bootstrap 867 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 868 869+-----------------------------------------------------------------------+ 870+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 871+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 872+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 873+-----------------------------------------------------------------------+ 874 875The compatibility shims for the build environment have been removed, you 876have to update to DragonFly 1.2 release branch first. 877 878The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 879The existing configuration can be converted using /etc/pam.d/convert.sh. 880Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 881the pam_skey.so module was retired, you have to remove it manually from 882your configuration, when you convert it. 883 884> Required user and group IDs when upgrading from either FreeBSD or DragonFly 885--------------------- 886 887The following users may be missing from your password file. Use vipw and 888add any that are missing: 889 890smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 891_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 892 893The following groups may be missing from your group file. Use vi /etc/group 894and add any that are missing: 895 896smmsp:*:25: 897authpf:*:63: 898_pflogd:*:64: 899 900 901> Upgrading to DragonFly from FreeBSD 902--------------------- 903 904You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 905FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 906FreeBSD. Note that the DragonFly buildworld target does not try to reuse 907make depend information, it starts from scratch, so no pre-cleaning of the 908object hierarchy is necessary. 909 910 # get the CVS repository (it is placed in /home/dcvs, 500MB). 911 # Please use the -h option and a mirror site to pull the 912 # initial repository, but feel free to use the main repository 913 # machine to pull updates. 914 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 915 # install the source from the CVS hierarchy (remove preexisting 916 # FreeBSD src first) (500MB) 917 cd /usr 918 rm -rf src 919 cvs -R -d /home/dcvs checkout -P src 920 921 # build it (500MB used in /usr/obj) 922 # 923 cd /usr/src 924 make buildworld 925 make buildkernel KERNCONF=<KERNELNAME> 926 927Once you have built DragonFly you have to install it over FreeBSD. Since 928DragonFly does not track changes made by FreeBSD to its include file 929hierarchy and include file pollution can cause all sorts of unexpected 930compilation issues to come up, it is best to wipe your include hierarchy 931prior to installing DragonFly. Note that you should not wipe any installed 932FreeBSD header files or binaries until after you have successfully completed 933the build steps above. 934 935 rm -rf /usr/include 936 mkdir /usr/include 937 make installkernel KERNCONF=<KERNELNAME> 938 make installworld 939 940Then you need to upgrade your system. DragonFly's 'make upgrade' target 941will unconditionally upgrade the /etc files that sysops do not usually 942mess around with, such as the files in /etc/rc.d. It will also remove any 943obsolete files such as utilities and manpages that have been removed from 944the system since the version you're coming from. If you are unsure we 945recommend that you make a backup of at least your /etc before applying 946this step. Note that DragonFly's RC system is basically RCNG from 947FreeBSD-5, but there are some differences in the contents of the RC files. 948 949 make upgrade 950 951NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 952Doing so might leave your system in an unusable state. 953 954Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 955/usr/bin, and /usr/lib, and remove any stale files that you find. Please 956report these files to the DragonFly developers so that they can be added to 957the 'upgrade' target. 958 959
