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 5.0 TO LATER VERSIONS + 13+-----------------------------------------------------------------------+ 14 15VARIOUS 'R' COMMANDS AND DAEMONS REMOVED 16---------------------------------------- 17 18rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed. 19For those that still need them, there is the net/bsdrcmds port. 20 21VARIOUS FORMER OPTIONS REMOVED 22------------------------------ 23 24Various former kernel configuration options which had been no-ops for 25some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B, 26_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in 27their kernel configuration files have to remove them. 28 29BOOTSTRAPPING LIMITED FROM PRE 4.4 30---------------------------------- 31 32Upgrading to 5.1 and later versions now require at least 4.4 in 33preparations for upcoming base compilers updates. 34 35IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED 36------------------------------------------ 37 38if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had 39already been removed from our default kernel configuration before 5.0, 40so only people with custom configurations based on earlier X86_64_GENERIC 41will have to remove it manually. 42 43The faith(4) interface has been completely removed after it had also 44been removed from our default kernel configuration. 45 46+-----------------------------------------------------------------------+ 47+ UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS + 48+-----------------------------------------------------------------------+ 49 50FFS_ROOT OPTION DISABLED 51------------------------ 52 53The FFS_ROOT option has been made a no-op and will be completely removed 54at some point in the future. Users with a custom kernel configuration 55can remove this option from it now. 56 57+-----------------------------------------------------------------------+ 58+ UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS + 59+-----------------------------------------------------------------------+ 60 61AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 62----------------------------------------------- 63 64They were all in our X86_64_GENERIC kernel configuration file, along with 65the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 66configuration files derived from it need adjustment. 67 68PORTAL FILE SYSTEM REMOVED 69-------------------------- 70 71It has been broken for a long time now. 72 73BINUTILS 2.27 REPLACES 2.24, PRIMARY 74------------------------------------ 75 76The oldest of the two versions of Binutils, version 2.24, was removed 77and replaced with Binutils 2.27. It becomes the primary version version 78of binutils and version 2.25 becomes the alternate. 79 80The accepted values of BINUTILSVER are now "binutils227" (default) and 81"binutils225". The building of Binutils 2.25 can be prevented by setting 82NO_ALTBINUTILS=yes in make.conf. 83 84COMPAT_43 KERNEL OPTION REMOVED 85------------------------------- 86 87It was commented out in our default configs for several years now, but 88might still be present in custom configs created before Nov. 2011. 89 90OPENSSL REMOVED 91--------------- 92 93OpenSSL has been removed from base and replaced with a private version of 94LibreSSL. The previously installed OpenSSL libraries, headers, and man 95pages will remain on the system unless the "make upgrade" command is 96specifically instructed to remove them. To do this, define 97REMOVE_OPENSSL_FILES for the upgrade command, e.g. 98"make upgrade REMOVE_OPENSSL_FILES=yes" 99 10028-Oct-2016: openssl has been replaced by ressl. It is recommended that any 101stale OpenSSL files be removed to avoid configuration scripts from using 102the stale and potentially vulnerable version, but all binaries that are 103dynamically linked to the OpenSSL libraries should be rebuilt first to 104avoid breakage. 105 106OPENSSH HPN REMOVED 107------------------- 108 109It has become too cumbersome to maintain HPN patches in OpenSSH in base. 110To use OpenSSH in base remove HPN config, if you have added it. 111Check files below for HPN config, see a few lines below. 112 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 113sshd(8) will fail to start if HPN config is used. 114 115NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 116 117HPN config: 118HPNDisabled 119HPNBufferSize 120TcpRcvBuf 121TcpRcvBufPoll 122NoneEnabled 123NoneSwitch 124cipher MTR-AES-CTR 125cipher NONE 126 127OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 128circumstances, especially for networking. 129If HPN functionality is needed, install security/openssh from dports. 130 131CS, EX AND VX DRIVERS REMOVED 132----------------------------- 133 134The cs(4), ex(4) and vx(4) drivers have been removed. They were very 135old and its doubtful they ever worked properly in x86_64 but they were 136in X86_64_GENERIC, so custom configurations derived from it have to be 137adjusted. 138 139+-----------------------------------------------------------------------+ 140+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 141+-----------------------------------------------------------------------+ 142 143AMD REMOVED 144----------- 145 146The am-utils automounter suite has been removed. It stopped working 147at some point and was never fixed. autofs(5) and the associated 148userland has been brought in from FreeBSD and replaces it. 149 150AN DRIVER REMOVED 151----------------- 152 153The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 154config file, so any configurations derived from it have to be adjusted. 155 156/DEV/DRI GROUP CHANGED 157---------------------- 158 159The default group assigned to /dev/dri entries has been changed 160from 'wheel' to 'video' with the id of '44'. If you want to have 161access to the dri devices please add yourself to the video group 162with: 163 164# pw groupmod video -m $USER 165 166+-----------------------------------------------------------------------+ 167+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 168+-----------------------------------------------------------------------+ 169 170DSCHED REMOVED 171-------------- 172 173dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 174in our default kernel config file. So the DSCHED_FQ option has been turned 175into a no-op for now and can be removed from custom configurations. 176 177EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 178------------------------------------------------- 179 180The est(4) driver has been removed. All CPUs it supported (except one) 181were 32 bits only. Those who are still using the Core 2 Duo T7500 should 182report back if there are any issues with this CPU and our regular ACPI 183P-state support. 184 185Also, compile_et(1) and com_err(3) have been removed as well. They 186should have been removed along with kerberos support, back in 2009. 187 188SEVERAL LOCALES RENAMED 189----------------------- 190 191Several locales were using obsolete and misleading names, and thus have 192been adjusted to current standards. Any users of the following locales 193need to select alternates: 194 195DFLY 4.2 locale DFLY 4.4 alterative locale 196--------------- ------------------------------------ 197mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 198no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 199no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 200no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 201sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 202sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 203sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 204zh_CN.GBK zh_Hans_CN.GBK 205zh_CN.UTF-8 zh_Hans_CN.UTF-8 206zh_CN.eucCN zh_Hans_CN.eucCN 207zh_CN.GB2312 zh_Hans_CH.GB2312 208zh_CN.GB18030 zh_Hans_CH.GB18030 209zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 210zh_HK.UTF_8 zh_Hant_HK.UTF-8 211zh_TW.Big5 zh_Hant_TW.Big5 212zh_TW.UTF-8 zh_Hant_TW.UTF-8 213 214+-----------------------------------------------------------------------+ 215+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 216+-----------------------------------------------------------------------+ 217 218BINUTILS 2.25 REPLACES 2.22, PRIMARY 219------------------------------------ 220 221The oldest of the two versions of Binutils, version 2.22, was removed 222and replaced with Binutils 2.25. It becomes the primary version version 223of binutils and version 2.24 becomes the alternate. There are 8 current 224CVE written against 2.24, so for security reasons version 2.25 should 225always be used. 226 227The accepted values of BINUTILSVER are now "binutils225" (default) and 228"binutils224". The building of Binutils 2.24 can be prevented by setting 229NO_ALTBINUTILS=yes in make.conf. 230 231LOADER OPTIONS CHANGED 232---------------------- 233 234Right after the development branch started, the Fred art accompanying the 235loader menu was improved. The line between Fred and the menu was removed 236by default (but can optionally be returned) and the placement shifted as 237a result. The drawing was improved, and the colored version was improved, 238changing the eyes and wing color from white to red. A new color version 239of Fred was added, one with a blue scheme. 240 241The loader menu defaults have changed since release 4.0: The vertical 242line was removed, the loader is displayed in color by default*, and the 243blue scheme is used. 244 245The loader.conf changes are: 246loader_color: option has been removed 247loader_plain: option has been added, it changed menu to monochrome 248fred_is_red: changes color scheme from blue to red 249fred_is_blue: option existed only on 4.1, it has been removed 250fred_separated: Adds line between Fred and menu (as seen previously) 251 252* If loader.conf defines "console" as "comconsole" or "console" is defined 253 in the environment as "comconsole" then color will not be displayed, 254 even if loader_plain value is "NO". 255 256SENDMAIL REMOVED FROM BASE 257-------------------------- 258 259The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 260If the system being upgraded is still configured to use the sendmail 261binaries from base, the "make upgrade" command will fail. 262 263The administrator must change /etc/mail/mailer.conf to switch the 264mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 265command that permanently removes sendmail executables and could 266potentially break a running mail server. 267 268Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 269detailed instructions on how to configure the MTA selection. 270 271_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 272-------------------------------------------- 273 274The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 275no-ops. They can be removed from custom kernel configurations. 276 277SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 278-------------------------------------------- 279 280Many more sound devices may be detected. 281 282If the default device choosen isn't to your liking, setting the sysctl 283hw.snd.default_unit to a different number will change it. 284 285SCTP SUPPORT DROPPED 286-------------------- 287 288Support for the SCTP protocol has been removed. 289 290OLD USB DRIVERS REMOVED 291----------------------- 292 293The old USB stack, along with the kernel config option "device oldusb" 294and the make.conf variable "WANT_OLDUSB" have been removed. This means 295that for custom kernel configuration files which were derived from a 296GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 297various (old USB stack specific) devices will now complain about being 298unknown: 299 300 * oldusb (obviously) 301 * natausb (not yet ported to usb4bsd) 302 * rue (not yet ported to usb4bsd) 303 * ugen (no longer needed in usb4bsd) 304 * urio (not yet ported to usb4bsd) 305 * uscanner (no longer needed in usb4bsd) 306 307They should be removed or commented out in such custom kernel configs. 308 309GCC 5 310----- 311 312The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 313The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 314NO_CXX. The latter was never documented and the latest versions of GCC are 315partially written in C++ so a C++ compiler is no longer optional. In 316practical terms it has not been optional for many years as other base 317components are also written in C++. The resource savings by avoiding 318building Objective-C compiler is so small, the complexity added by NO_OBJC 319internally was deemed a bad tradeoff so that is the reason for its removal. 320Also note that no "info" pages are installed with GCC 5. After this entry 321was originally written, all info pages were removed from DragonFly. 322 323GCC 5.1 has been designated as the primary compiler. As such, there is a 324new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 325the designated secondary compiler, GCC 4.7. However, while DPorts 326primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 327if building ports from source is desired, don't block building of the 328secondary compiler. 329 330+-----------------------------------------------------------------------+ 331+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 332+-----------------------------------------------------------------------+ 333 334SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 335------------------------------------------- 336 337DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 338the default now (even on single-core systems), both for, like, 21 months. 339We kept the options around as no-ops as a convenience, to allow people 340using the same config for the then current release and the then current 341master. That period is now over, so any configs still having those 342options have to be adjusted. 343 344SYSVIPC SYSCALLS MADE NON-OPTIONAL 345---------------------------------- 346 347The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 348now compiled in by default. The options are no-ops for now. 349 350DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 351-------------------------------------------------------------------- 352 353The default driver for those controllers is now mrsas(4) due to reports 354of file system corruption using the mfi(4) driver. The whole issue (and 355how to deal with potential problems when switching) was explained here: 356 357http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 358 359A tunable is provided for letting those controllers still attach via 360the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 361 362OLDER NETWORK DRIVERS MOVED TO I386 ONLY 363---------------------------------------- 364 365The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 366and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 367removed in kernel configs derived from X86_64_GENERIC. 368 369+-----------------------------------------------------------------------+ 370+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 371+-----------------------------------------------------------------------+ 372 373UPDATE FROM MOST RECENT 3.6 374--------------------------- 375 376Versions of 3.6 built before June 25th have a bug where installworld might 377crash during installation of the new initrd. Upgrade to the latest version 378of 3.6 before updating to 3.8 or later. 379 380ATM, IPX, NCP AND NWFS SUPPORT DROPPED 381-------------------------------------- 382 383Support for the IPX and NCP network protocols and for mouting NetWare 384file systems has been dropped. Dito for ATM protocol support. 385 386INITRD IMAGES NOW INSTALLED BY DEFAULT 387-------------------------------------- 388 389An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 390 391Older images installed under the file name of initrd.img will be removed 392automatically by the make upgrade process. 393 394USB4BSD IS NOW THE DEFAULT USB STACK 395------------------------------------ 396 397To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 398replace "device usb" with "device oldusb" in the kernel configuration. 399 400MORE ISA SUPPORT DROPPED 401------------------------ 402 403ISA support has been dropped from the following drivers: adv(4), an(4), 404ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 405si(4), sn(4), and stg(4). 406 407+-----------------------------------------------------------------------+ 408+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 409+-----------------------------------------------------------------------+ 410 411ABI CHANGE 412---------- 413 414Installed third-party software (dports) will have to be rebuilt after upgrade, 415or reinstalled from binary packages. 416 417UPDATING FROM 3.4 TO 3.6 418------------------------ 419 420This only applies for this specific upgrade due to locale changes; it is 421not needed for upgrades after 3.6. Please update in this order: 422 423make buildworld 424make buildkernel 425make installworld 426make installkernel 427*reboot* 428make upgrade 429 430See this mailing list post for details: 431http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 432 433CYRIX OPTIONS REMOVED 434--------------------- 435 436The following Cyrix related options have been removed: CPU_BTB_EN, 437CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 438CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 439CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 440 441ISA SUPPORT REMOVED FROM RP(4) 442------------------------------ 443 444ISA support has been removed from the rp(4) driver. It is now PCI only. 445 446+-----------------------------------------------------------------------+ 447+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 448+-----------------------------------------------------------------------+ 449 450COMPAT_SUNOS OPTION REMOVED 451--------------------------- 452 453The COMPAT_SUNOS option has been removed. It was meant to provide binary 454compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 455 456ISA SOUND CARD SUPPORT REMOVED 457------------------------------ 458 459The following modules have been removed (all for ISA sound cards): 460snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 461 462GCC 4.7 463------- 464 465DragonFly has switched base compilers. GCC 4.7 is now the default 466compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 467variable ceases to work now. 468 469Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 470/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 471highly discouraged. There are a few packages in pkgsrc that do not build 472with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 473this time, it is recommended to keep both compilers on the base system. 474 475SMP OPTION REMOVED 476------------------ 477 478The SMP kernel option has been made a no-op. All kernels now feature SMP 479support. If you have 'options SMP' in your kernel config, you can as well 480remove it. 481 482DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 483--------------------------------------------------------------------------- 484 485The DEVICE_POLLING kernel option has been made a no-op and it has been 486replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 487kernel config, you need to change it to IFPOLL_ENABLE. 488 489Also, the KTR_POLLING kernel option has been removed, so it must be 490removed from kernel configs that have it. 491 492BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 493--------------------------------------------------- 494 495The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 496cards will no longer be detected. 497 498The same has been done for Stallion multiport serial controllers. stli(4) 499has been completely removed (along with the stlload(8) and stlstty(8) 500utilities) and stl(4) was changed to support only PCI cards. Similarly, 501ISA support was removed from cy(4) too. All these drivers are i386 only. 502 503COMPAT_OLDISA OPTION GONE 504------------------------- 505 506The i386 specific COMPAT_OLDISA kernel option has been removed, since 507nothing needs it anymore. 508 509+-----------------------------------------------------------------------+ 510+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 511+-----------------------------------------------------------------------+ 512 513APIC_IO OPTION REMOVED 514---------------------- 515 516The APIC_IO kernel option is no longer accepted after having been without 517effect for a while. The hw.ioapic_enable tunable now serves its purpose. 518If you have 'options APIC_IO' in your kernel config, you'll have to 519remove it. 520 521WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 522----------------------------------------- 523 524The wdog framework is now compiled into our kernels by default, so the 525options are no longer needed. 526 527DOSCMD(1) REMOVED 528----------------- 529 530doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 531NO_X make.conf option was removed too. 532 533GCC 4.7 534------- 535 536GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 537default compiler in base (default is still GCC 4.4). 538 539Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 540NO_GCC47 in /etc/make.conf. 541 542USB4BSD 543------- 544 545A new USB stack (from FreeBSD) has been brought in. The following 546modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 547usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 548and uaudio. 549 550It is not yet the default. To activate it, WANT_USB4BSD=yes has to 551be put in make.conf and device "usb4bsd" (quotes needed) has to 552replace device usb in the kernel config. After that, a full 553build/install/upgrade cycle is needed. 554 555Note that this is experimental and incomplete, but we are interested 556in hearing about issues with it, of course. 557 558ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 559--------------------------------------------- 560 561ISA adapter support was dropped from the aic(4) driver. 562 563+-----------------------------------------------------------------------+ 564+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 565+-----------------------------------------------------------------------+ 566 567SEVERAL ISA DRIVERS REMOVED 568--------------------------- 569 570The following ISA only drivers have been removed along with a couple of 571associated userland tools: 572 573aha(4) 574asc(4) & sasc(1) 575ctx 576dgb(4) 577el(4) 578gpib 579gsc(4) & sgsc(1) 580ie(4) 581labpc(4) 582le(4) 583mse(4) 584rc(4) 585rdp(4) 586spigot 587tw(4) & xten(1) & xtend(8) 588wl(4) & wlconfig(8) 589wt(4) 590 591Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 592config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 593file. 594 595If buildkernel complains about any of these drivers, just remove them 596from your kernel configuration. 597 598BINUTILS 2.20 599------------- 600Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 601values of BINUTILSVERS are now binutils221 and binutils222 (default). 602 603BUILDWORLD/-KERNEL PARALLELIZATION WORK 604--------------------------------------- 605Due to changes in the way we build with more than one make job, you 606will have to update install(1) and mkdir(1) prior to buildworld if you 607want to build with 'make -j': 608 609cd /usr/src/usr.bin/xinstall; make; make install; make clean 610cd /usr/src/bin/mkdir; make; make install; make clean 611 612DMA(8) UPGRADE 613-------------- 614dma(8) has been upgraded to v0.7 which no longer supports the 615/etc/dma/virtusertable. Some of its functionality has been replaced 616with the MASQUERADE keyword and the EMAIL environment variable (see 617the dma(8) manual page). 618 619+-----------------------------------------------------------------------+ 620+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 621+-----------------------------------------------------------------------+ 622 623GCC 4.4 & BINUTILS 2.21 624----------------------- 625 626GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 627been made DragonFly's default Binutils. 628 629That means that any settings that set CCVER to 'gcc44' are not needed 630anymore. Instead, CCVER can be set to 'gcc41' to go back to using 631GCC 4.1. 632 633It also means that 'binutils221' as a value for BINUTILSVER has no 634effect anymore. 2.17 has been removed and 'binutils220' is available 635as an option. 636 637The NO_GCC44 option has been removed and will not affect the build 638anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 639building in a similar fashion. 640 641Note that you must do a full buildworld/buildkernel for upgrading. 642 643pkg_radd settings 644----------------- 645 646The config file for pkg_radd has moved from /etc/settings.conf to 647/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 648if this is needed. This warning only applies if /etc/settings.conf 649exists. pkg_radd will continue to work with defaults. 650 651+-----------------------------------------------------------------------+ 652+ 20100927 + 653+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 654+-----------------------------------------------------------------------+ 655 656OpenSSL 657-------- 658 659OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 660This shouldn't break any 3rd-party software, but you'll need to recompile your 6613rd-party software if you want it to link against the new version of OpenSSL. 662 663Loader 664------- 665 666A new loader (dloader) has been added which better handles booting from 667multiple kernel/module versions. 668 669To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 670 671 cd /usr/src 672 make buildworld 673 make installworld 674 make upgrade 675 make buildkernel KERNCONF=<KERNELNAME> 676 make installkernel KERNCONF=<KERNELNAME> 677 678Note that you must installworld and run the 'upgrade' target before 679installing the new kernel. 680 681BIND 682----- 683 684BIND has been removed from the base system. The ldns and drill tools have 685been added for basic functionality. Use 'drill' where you would normally 686use nslookup or dig, or install BIND from pkgsrc. It's available as 687net/bind95, net/bind96, or net/bind97 as of this writing. 688 689This only affects older systems upgrading to 2.8. New 2.8+ installs 690include BIND as a pkgsrc package. 691 692+-----------------------------------------------------------------------+ 693+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 694+ GENERAL + 695+-----------------------------------------------------------------------+ 696 697Instructions on how to obtain and maintain DragonFly source code using git 698are in the development(7) manual page. 699 700To upgrade a DragonFly system from sources you run the following sequence: 701 702 cd /usr/src 703 make buildworld 704 make buildkernel KERNCONF=<KERNELNAME> 705 make installkernel KERNCONF=<KERNELNAME> 706 make installworld 707 708You will also want to run the 'upgrade' target to upgrade your /etc and the 709rest of your system. The upgrade target is aware of stale files created by 710older DragonFly installations and should delete them automatically. 711 712 make upgrade 713 714See the build(7) manual page for further information. 715 716Once you've done a full build of the world and kernel you can do incremental 717upgrades of either by using the 'quickworld' and 'quickkernel' targets 718instead of 'buildworld' and 'buildkernel'. If you have any problems with 719the quick targets, try updating your repo first, and then a full buildworld 720and buildkernel as shown above, before asking for help. 721 722+-----------------------------------------------------------------------+ 723+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 724+-----------------------------------------------------------------------+ 725 726In 2.1 kernel and modules has moved to boot directory. For most cases 727this is handled automatically by 'make upgrade'. A few cases needs manual 728intervention: 729 730 * When installing a kernel without first doing a make buildworld, 731 installworld and upgrade to the same DESTDIR as kernel: 732 make DESTDIR/boot directory and move kernel and modules into this boot 733 directory; also move kernel.old and modules.old. 734 Typical example is vkernel(7), use (no modules used): 735 736 cd /var/vkernel 737 mkdir boot 738 chflags noschg kernel 739 mv kernel kernel.old boot 740 chflags schg boot/kernel 741 742 * When using a boot-only partition, /boot/loader.rc needs to be edited: 743 delete occurrences of '/boot/'. 744 These occurences can normally be deleted in any case, see loader(8). 745 746+-----------------------------------------------------------------------+ 747+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 748+-----------------------------------------------------------------------+ 749 750In 1.9 major changes to the disk management infrastructure have taken 751place. make upgrade may not catch all of your disk devices in /dev, 752so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 753are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 754and MAKEDEV no longer exists. 755 756The biggest changes in 1.9 are: 757 758(1) That whole-slice devices such as da0s1 no longer share the same device 759 id as partition c devices such as da0s1c. 760 761(2) The whole-disk device (e.g. da0) is full raw access to the disk, 762 with no snooping or reserved sectors. Consequently you cannot run 763 disklabel on this device. Instead you must run disklabel on a 764 whole-slice device. 765 766(3) The 'compatibility' partitions now use slice 0 in the device name, 767 so instead of da0a you must specify da0s0a. Also, as per (1) above, 768 accessing the disklabel for the compatibility partitions must be 769 done via slice 0 (da0s0). 770 771(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 772 and CCD now run through the disk management layer and are assigned 773 real disk management devices. VN and CCD in particular do not usually 774 use a MBR and disklabels must be accessed through the compatibility 775 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 776 don't name it 'ccd0s0' in the config file. 777 778Generally speaking, you have to get used to running fdisk and disklabel on 779the correctly specified device names. A lot of the wiggle, such as running 780disklabel on a partition, has been removed. 781 782+-----------------------------------------------------------------------+ 783+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 784+-----------------------------------------------------------------------+ 785 786> Kerberos IV 787------------- 788 789Kerberos IV (eBones) was removed from the tree, please consider moving to 790Kerberos 5 (Heimdal). 791 792> Package Management System 793--------------------------- 794 795Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 796management system. The necessary tools to build and maintain packages 797are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 798directories are in your PATH variable. 799 800In order to obtain a reasonably current snapshot of the pkgsrc tree, use 801the tarball from NetBSD: 802 803 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 804 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 805 806This tree can then be kept up to date with cvs update: 807 808 cd /usr/pkgsrc; cvs up 809 810NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 811build and install the pkgsrc bootstrap manually: 812 813 cd /usr/pkgsrc/bootstrap 814 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 815 816+-----------------------------------------------------------------------+ 817+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 818+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 819+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 820+-----------------------------------------------------------------------+ 821 822The compatibility shims for the build environment have been removed, you 823have to update to DragonFly 1.2 release branch first. 824 825The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 826The existing configuration can be converted using /etc/pam.d/convert.sh. 827Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 828the pam_skey.so module was retired, you have to remove it manually from 829your configuration, when you convert it. 830 831> Required user and group IDs when upgrading from either FreeBSD or DragonFly 832--------------------- 833 834The following users may be missing from your password file. Use vipw and 835add any that are missing: 836 837smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 838_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 839 840The following groups may be missing from your group file. Use vi /etc/group 841and add any that are missing: 842 843smmsp:*:25: 844authpf:*:63: 845_pflogd:*:64: 846 847 848> Upgrading to DragonFly from FreeBSD 849--------------------- 850 851You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 852FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 853FreeBSD. Note that the DragonFly buildworld target does not try to reuse 854make depend information, it starts from scratch, so no pre-cleaning of the 855object hierarchy is necessary. 856 857 # get the CVS repository (it is placed in /home/dcvs, 500MB). 858 # Please use the -h option and a mirror site to pull the 859 # initial repository, but feel free to use the main repository 860 # machine to pull updates. 861 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 862 # install the source from the CVS hierarchy (remove preexisting 863 # FreeBSD src first) (500MB) 864 cd /usr 865 rm -rf src 866 cvs -R -d /home/dcvs checkout -P src 867 868 # build it (500MB used in /usr/obj) 869 # 870 cd /usr/src 871 make buildworld 872 make buildkernel KERNCONF=<KERNELNAME> 873 874Once you have built DragonFly you have to install it over FreeBSD. Since 875DragonFly does not track changes made by FreeBSD to its include file 876hierarchy and include file pollution can cause all sorts of unexpected 877compilation issues to come up, it is best to wipe your include hierarchy 878prior to installing DragonFly. Note that you should not wipe any installed 879FreeBSD header files or binaries until after you have successfully completed 880the build steps above. 881 882 rm -rf /usr/include 883 mkdir /usr/include 884 make installkernel KERNCONF=<KERNELNAME> 885 make installworld 886 887Then you need to upgrade your system. DragonFly's 'make upgrade' target 888will unconditionally upgrade the /etc files that sysops do not usually 889mess around with, such as the files in /etc/rc.d. It will also remove any 890obsolete files such as utilities and manpages that have been removed from 891the system since the version you're coming from. If you are unsure we 892recommend that you make a backup of at least your /etc before applying 893this step. Note that DragonFly's RC system is basically RCNG from 894FreeBSD-5, but there are some differences in the contents of the RC files. 895 896 make upgrade 897 898NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 899Doing so might leave your system in an unusable state. 900 901Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 902/usr/bin, and /usr/lib, and remove any stale files that you find. Please 903report these files to the DragonFly developers so that they can be added to 904the 'upgrade' target. 905 906
