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 4.6 TO LATER VERSIONS + 13+-----------------------------------------------------------------------+ 14 15AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 16----------------------------------------------- 17 18They were all in our X86_64_GENERIC kernel configuration file, along with 19the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 20configuration files derived from it need adjustment. 21 22PORTAL FILE SYSTEM REMOVED 23-------------------------- 24 25It has been broken for a long time now. 26 27BINUTILS 2.27 REPLACES 2.24, PRIMARY 28------------------------------------ 29 30The oldest of the two versions of Binutils, version 2.24, was removed 31and replaced with Binutils 2.27. It becomes the primary version version 32of binutils and version 2.25 becomes the alternate. 33 34The accepted values of BINUTILSVER are now "binutils227" (default) and 35"binutils225". The building of Binutils 2.25 can be prevented by setting 36NO_ALTBINUTILS=yes in make.conf. 37 38COMPAT_43 KERNEL OPTION REMOVED 39------------------------------- 40 41It was commented out in our default configs for several years now, but 42might still be present in custom configs created before Nov. 2011. 43 44OPENSSL REMOVED 45--------------- 46 47OpenSSL has been removed from base and replaced with a private version of 48LibreSSL. The previously installed OpenSSL libraries, headers, and man 49pages will remain on the system unless the "make upgrade" command is 50specifically instructed to remove them. To do this, define 51REMOVE_OPENSSL_FILES for the upgrade command, e.g. 52"make upgrade REMOVE_OPENSSL_FILES=yes" 53 5428-Oct-2016: openssl has been replaced by ressl. It is recommended that any 55stale OpenSSL files be removed to avoid configuration scripts from using 56the stale and potentially vulnerable version, but all binaries that are 57dynamically linked to the OpenSSL libraries should be rebuilt first to 58avoid breakage. 59 60OPENSSH HPN REMOVED 61------------------- 62 63It has become too cumbersome to maintain HPN patches in OpenSSH in base. 64To use OpenSSH in base remove HPN config, if you have added it. 65Check files below for HPN config, see a few lines below. 66 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 67sshd(8) will fail to start if HPN config is used. 68 69NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 70 71HPN config: 72HPNDisabled 73HPNBufferSize 74TcpRcvBuf 75TcpRcvBufPoll 76NoneEnabled 77NoneSwitch 78cipher MTR-AES-CTR 79cipher NONE 80 81OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 82circumstances, especially for networking. 83If HPN functionality is needed, install security/openssh from dports. 84 85CS, EX AND VX DRIVERS REMOVED 86----------------------------- 87 88The cs(4), ex(4) and vx(4) drivers have been removed. They were very 89old and its doubtful they ever worked properly in x86_64 but they were 90in X86_64_GENERIC, so custom configurations derived from it have to be 91adjusted. 92 93+-----------------------------------------------------------------------+ 94+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 95+-----------------------------------------------------------------------+ 96 97AMD REMOVED 98----------- 99 100The am-utils automounter suite has been removed. It stopped working 101at some point and was never fixed. autofs(5) and the associated 102userland has been brought in from FreeBSD and replaces it. 103 104AN DRIVER REMOVED 105----------------- 106 107The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 108config file, so any configurations derived from it have to be adjusted. 109 110/DEV/DRI GROUP CHANGED 111---------------------- 112 113The default group assigned to /dev/dri entries has been changed 114from 'wheel' to 'video' with the id of '44'. If you want to have 115access to the dri devices please add yourself to the video group 116with: 117 118# pw groupmod video -m $USER 119 120+-----------------------------------------------------------------------+ 121+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 122+-----------------------------------------------------------------------+ 123 124DSCHED REMOVED 125-------------- 126 127dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 128in our default kernel config file. So the DSCHED_FQ option has been turned 129into a no-op for now and can be removed from custom configurations. 130 131EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 132------------------------------------------------- 133 134The est(4) driver has been removed. All CPUs it supported (except one) 135were 32 bits only. Those who are still using the Core 2 Duo T7500 should 136report back if there are any issues with this CPU and our regular ACPI 137P-state support. 138 139Also, compile_et(1) and com_err(3) have been removed as well. They 140should have been removed along with kerberos support, back in 2009. 141 142SEVERAL LOCALES RENAMED 143----------------------- 144 145Several locales were using obsolete and misleading names, and thus have 146been adjusted to current standards. Any users of the following locales 147need to select alternates: 148 149DFLY 4.2 locale DFLY 4.4 alterative locale 150--------------- ------------------------------------ 151mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 152no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 153no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 154no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 155sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 156sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 157sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 158zh_CN.GBK zh_Hans_CN.GBK 159zh_CN.UTF-8 zh_Hans_CN.UTF-8 160zh_CN.eucCN zh_Hans_CN.eucCN 161zh_CN.GB2312 zh_Hans_CH.GB2312 162zh_CN.GB18030 zh_Hans_CH.GB18030 163zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 164zh_HK.UTF_8 zh_Hant_HK.UTF-8 165zh_TW.Big5 zh_Hant_TW.Big5 166zh_TW.UTF-8 zh_Hant_TW.UTF-8 167 168+-----------------------------------------------------------------------+ 169+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 170+-----------------------------------------------------------------------+ 171 172BINUTILS 2.25 REPLACES 2.22, PRIMARY 173------------------------------------ 174 175The oldest of the two versions of Binutils, version 2.22, was removed 176and replaced with Binutils 2.25. It becomes the primary version version 177of binutils and version 2.24 becomes the alternate. There are 8 current 178CVE written against 2.24, so for security reasons version 2.25 should 179always be used. 180 181The accepted values of BINUTILSVER are now "binutils225" (default) and 182"binutils224". The building of Binutils 2.24 can be prevented by setting 183NO_ALTBINUTILS=yes in make.conf. 184 185LOADER OPTIONS CHANGED 186---------------------- 187 188Right after the development branch started, the Fred art accompanying the 189loader menu was improved. The line between Fred and the menu was removed 190by default (but can optionally be returned) and the placement shifted as 191a result. The drawing was improved, and the colored version was improved, 192changing the eyes and wing color from white to red. A new color version 193of Fred was added, one with a blue scheme. 194 195The loader menu defaults have changed since release 4.0: The vertical 196line was removed, the loader is displayed in color by default*, and the 197blue scheme is used. 198 199The loader.conf changes are: 200loader_color: option has been removed 201loader_plain: option has been added, it changed menu to monochrome 202fred_is_red: changes color scheme from blue to red 203fred_is_blue: option existed only on 4.1, it has been removed 204fred_separated: Adds line between Fred and menu (as seen previously) 205 206* If loader.conf defines "console" as "comconsole" or "console" is defined 207 in the environment as "comconsole" then color will not be displayed, 208 even if loader_plain value is "NO". 209 210SENDMAIL REMOVED FROM BASE 211-------------------------- 212 213The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 214If the system being upgraded is still configured to use the sendmail 215binaries from base, the "make upgrade" command will fail. 216 217The administrator must change /etc/mail/mailer.conf to switch the 218mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 219command that permanently removes sendmail executables and could 220potentially break a running mail server. 221 222Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 223detailed instructions on how to configure the MTA selection. 224 225_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 226-------------------------------------------- 227 228The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 229no-ops. They can be removed from custom kernel configurations. 230 231SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 232-------------------------------------------- 233 234Many more sound devices may be detected. 235 236If the default device choosen isn't to your liking, setting the sysctl 237hw.snd.default_unit to a different number will change it. 238 239SCTP SUPPORT DROPPED 240-------------------- 241 242Support for the SCTP protocol has been removed. 243 244OLD USB DRIVERS REMOVED 245----------------------- 246 247The old USB stack, along with the kernel config option "device oldusb" 248and the make.conf variable "WANT_OLDUSB" have been removed. This means 249that for custom kernel configuration files which were derived from a 250GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 251various (old USB stack specific) devices will now complain about being 252unknown: 253 254 * oldusb (obviously) 255 * natausb (not yet ported to usb4bsd) 256 * rue (not yet ported to usb4bsd) 257 * ugen (no longer needed in usb4bsd) 258 * urio (not yet ported to usb4bsd) 259 * uscanner (no longer needed in usb4bsd) 260 261They should be removed or commented out in such custom kernel configs. 262 263GCC 5 264----- 265 266The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 267The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 268NO_CXX. The latter was never documented and the latest versions of GCC are 269partially written in C++ so a C++ compiler is no longer optional. In 270practical terms it has not been optional for many years as other base 271components are also written in C++. The resource savings by avoiding 272building Objective-C compiler is so small, the complexity added by NO_OBJC 273internally was deemed a bad tradeoff so that is the reason for its removal. 274Also note that no "info" pages are installed with GCC 5. After this entry 275was originally written, all info pages were removed from DragonFly. 276 277GCC 5.1 has been designated as the primary compiler. As such, there is a 278new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 279the designated secondary compiler, GCC 4.7. However, while DPorts 280primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 281if building ports from source is desired, don't block building of the 282secondary compiler. 283 284+-----------------------------------------------------------------------+ 285+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 286+-----------------------------------------------------------------------+ 287 288SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 289------------------------------------------- 290 291DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 292the default now (even on single-core systems), both for, like, 21 months. 293We kept the options around as no-ops as a convenience, to allow people 294using the same config for the then current release and the then current 295master. That period is now over, so any configs still having those 296options have to be adjusted. 297 298SYSVIPC SYSCALLS MADE NON-OPTIONAL 299---------------------------------- 300 301The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 302now compiled in by default. The options are no-ops for now. 303 304DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 305-------------------------------------------------------------------- 306 307The default driver for those controllers is now mrsas(4) due to reports 308of file system corruption using the mfi(4) driver. The whole issue (and 309how to deal with potential problems when switching) was explained here: 310 311http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 312 313A tunable is provided for letting those controllers still attach via 314the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 315 316OLDER NETWORK DRIVERS MOVED TO I386 ONLY 317---------------------------------------- 318 319The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 320and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 321removed in kernel configs derived from X86_64_GENERIC. 322 323+-----------------------------------------------------------------------+ 324+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 325+-----------------------------------------------------------------------+ 326 327UPDATE FROM MOST RECENT 3.6 328--------------------------- 329 330Versions of 3.6 built before June 25th have a bug where installworld might 331crash during installation of the new initrd. Upgrade to the latest version 332of 3.6 before updating to 3.8 or later. 333 334ATM, IPX, NCP AND NWFS SUPPORT DROPPED 335-------------------------------------- 336 337Support for the IPX and NCP network protocols and for mouting NetWare 338file systems has been dropped. Dito for ATM protocol support. 339 340INITRD IMAGES NOW INSTALLED BY DEFAULT 341-------------------------------------- 342 343An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 344 345Older images installed under the file name of initrd.img will be removed 346automatically by the make upgrade process. 347 348USB4BSD IS NOW THE DEFAULT USB STACK 349------------------------------------ 350 351To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 352replace "device usb" with "device oldusb" in the kernel configuration. 353 354MORE ISA SUPPORT DROPPED 355------------------------ 356 357ISA support has been dropped from the following drivers: adv(4), an(4), 358ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 359si(4), sn(4), and stg(4). 360 361+-----------------------------------------------------------------------+ 362+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 363+-----------------------------------------------------------------------+ 364 365ABI CHANGE 366---------- 367 368Installed third-party software (dports) will have to be rebuilt after upgrade, 369or reinstalled from binary packages. 370 371UPDATING FROM 3.4 TO 3.6 372------------------------ 373 374This only applies for this specific upgrade due to locale changes; it is 375not needed for upgrades after 3.6. Please update in this order: 376 377make buildworld 378make buildkernel 379make installworld 380make installkernel 381*reboot* 382make upgrade 383 384See this mailing list post for details: 385http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 386 387CYRIX OPTIONS REMOVED 388--------------------- 389 390The following Cyrix related options have been removed: CPU_BTB_EN, 391CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 392CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 393CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 394 395ISA SUPPORT REMOVED FROM RP(4) 396------------------------------ 397 398ISA support has been removed from the rp(4) driver. It is now PCI only. 399 400+-----------------------------------------------------------------------+ 401+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 402+-----------------------------------------------------------------------+ 403 404COMPAT_SUNOS OPTION REMOVED 405--------------------------- 406 407The COMPAT_SUNOS option has been removed. It was meant to provide binary 408compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 409 410ISA SOUND CARD SUPPORT REMOVED 411------------------------------ 412 413The following modules have been removed (all for ISA sound cards): 414snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 415 416GCC 4.7 417------- 418 419DragonFly has switched base compilers. GCC 4.7 is now the default 420compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 421variable ceases to work now. 422 423Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 424/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 425highly discouraged. There are a few packages in pkgsrc that do not build 426with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 427this time, it is recommended to keep both compilers on the base system. 428 429SMP OPTION REMOVED 430------------------ 431 432The SMP kernel option has been made a no-op. All kernels now feature SMP 433support. If you have 'options SMP' in your kernel config, you can as well 434remove it. 435 436DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 437--------------------------------------------------------------------------- 438 439The DEVICE_POLLING kernel option has been made a no-op and it has been 440replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 441kernel config, you need to change it to IFPOLL_ENABLE. 442 443Also, the KTR_POLLING kernel option has been removed, so it must be 444removed from kernel configs that have it. 445 446BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 447--------------------------------------------------- 448 449The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 450cards will no longer be detected. 451 452The same has been done for Stallion multiport serial controllers. stli(4) 453has been completely removed (along with the stlload(8) and stlstty(8) 454utilities) and stl(4) was changed to support only PCI cards. Similarly, 455ISA support was removed from cy(4) too. All these drivers are i386 only. 456 457COMPAT_OLDISA OPTION GONE 458------------------------- 459 460The i386 specific COMPAT_OLDISA kernel option has been removed, since 461nothing needs it anymore. 462 463+-----------------------------------------------------------------------+ 464+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 465+-----------------------------------------------------------------------+ 466 467APIC_IO OPTION REMOVED 468---------------------- 469 470The APIC_IO kernel option is no longer accepted after having been without 471effect for a while. The hw.ioapic_enable tunable now serves its purpose. 472If you have 'options APIC_IO' in your kernel config, you'll have to 473remove it. 474 475WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 476----------------------------------------- 477 478The wdog framework is now compiled into our kernels by default, so the 479options are no longer needed. 480 481DOSCMD(1) REMOVED 482----------------- 483 484doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 485NO_X make.conf option was removed too. 486 487GCC 4.7 488------- 489 490GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 491default compiler in base (default is still GCC 4.4). 492 493Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 494NO_GCC47 in /etc/make.conf. 495 496USB4BSD 497------- 498 499A new USB stack (from FreeBSD) has been brought in. The following 500modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 501usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 502and uaudio. 503 504It is not yet the default. To activate it, WANT_USB4BSD=yes has to 505be put in make.conf and device "usb4bsd" (quotes needed) has to 506replace device usb in the kernel config. After that, a full 507build/install/upgrade cycle is needed. 508 509Note that this is experimental and incomplete, but we are interested 510in hearing about issues with it, of course. 511 512ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 513--------------------------------------------- 514 515ISA adapter support was dropped from the aic(4) driver. 516 517+-----------------------------------------------------------------------+ 518+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 519+-----------------------------------------------------------------------+ 520 521SEVERAL ISA DRIVERS REMOVED 522--------------------------- 523 524The following ISA only drivers have been removed along with a couple of 525associated userland tools: 526 527aha(4) 528asc(4) & sasc(1) 529ctx 530dgb(4) 531el(4) 532gpib 533gsc(4) & sgsc(1) 534ie(4) 535labpc(4) 536le(4) 537mse(4) 538rc(4) 539rdp(4) 540spigot 541tw(4) & xten(1) & xtend(8) 542wl(4) & wlconfig(8) 543wt(4) 544 545Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 546config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 547file. 548 549If buildkernel complains about any of these drivers, just remove them 550from your kernel configuration. 551 552BINUTILS 2.20 553------------- 554Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 555values of BINUTILSVERS are now binutils221 and binutils222 (default). 556 557BUILDWORLD/-KERNEL PARALLELIZATION WORK 558--------------------------------------- 559Due to changes in the way we build with more than one make job, you 560will have to update install(1) and mkdir(1) prior to buildworld if you 561want to build with 'make -j': 562 563cd /usr/src/usr.bin/xinstall; make; make install; make clean 564cd /usr/src/bin/mkdir; make; make install; make clean 565 566DMA(8) UPGRADE 567-------------- 568dma(8) has been upgraded to v0.7 which no longer supports the 569/etc/dma/virtusertable. Some of its functionality has been replaced 570with the MASQUERADE keyword and the EMAIL environment variable (see 571the dma(8) manual page). 572 573+-----------------------------------------------------------------------+ 574+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 575+-----------------------------------------------------------------------+ 576 577GCC 4.4 & BINUTILS 2.21 578----------------------- 579 580GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 581been made DragonFly's default Binutils. 582 583That means that any settings that set CCVER to 'gcc44' are not needed 584anymore. Instead, CCVER can be set to 'gcc41' to go back to using 585GCC 4.1. 586 587It also means that 'binutils221' as a value for BINUTILSVER has no 588effect anymore. 2.17 has been removed and 'binutils220' is available 589as an option. 590 591The NO_GCC44 option has been removed and will not affect the build 592anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 593building in a similar fashion. 594 595Note that you must do a full buildworld/buildkernel for upgrading. 596 597pkg_radd settings 598----------------- 599 600The config file for pkg_radd has moved from /etc/settings.conf to 601/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 602if this is needed. This warning only applies if /etc/settings.conf 603exists. pkg_radd will continue to work with defaults. 604 605+-----------------------------------------------------------------------+ 606+ 20100927 + 607+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 608+-----------------------------------------------------------------------+ 609 610OpenSSL 611-------- 612 613OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 614This shouldn't break any 3rd-party software, but you'll need to recompile your 6153rd-party software if you want it to link against the new version of OpenSSL. 616 617Loader 618------- 619 620A new loader (dloader) has been added which better handles booting from 621multiple kernel/module versions. 622 623To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 624 625 cd /usr/src 626 make buildworld 627 make installworld 628 make upgrade 629 make buildkernel KERNCONF=<KERNELNAME> 630 make installkernel KERNCONF=<KERNELNAME> 631 632Note that you must installworld and run the 'upgrade' target before 633installing the new kernel. 634 635BIND 636----- 637 638BIND has been removed from the base system. The ldns and drill tools have 639been added for basic functionality. Use 'drill' where you would normally 640use nslookup or dig, or install BIND from pkgsrc. It's available as 641net/bind95, net/bind96, or net/bind97 as of this writing. 642 643This only affects older systems upgrading to 2.8. New 2.8+ installs 644include BIND as a pkgsrc package. 645 646+-----------------------------------------------------------------------+ 647+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 648+ GENERAL + 649+-----------------------------------------------------------------------+ 650 651Instructions on how to obtain and maintain DragonFly source code using git 652are in the development(7) manual page. 653 654To upgrade a DragonFly system from sources you run the following sequence: 655 656 cd /usr/src 657 make buildworld 658 make buildkernel KERNCONF=<KERNELNAME> 659 make installkernel KERNCONF=<KERNELNAME> 660 make installworld 661 662You will also want to run the 'upgrade' target to upgrade your /etc and the 663rest of your system. The upgrade target is aware of stale files created by 664older DragonFly installations and should delete them automatically. 665 666 make upgrade 667 668See the build(7) manual page for further information. 669 670Once you've done a full build of the world and kernel you can do incremental 671upgrades of either by using the 'quickworld' and 'quickkernel' targets 672instead of 'buildworld' and 'buildkernel'. If you have any problems with 673the quick targets, try updating your repo first, and then a full buildworld 674and buildkernel as shown above, before asking for help. 675 676+-----------------------------------------------------------------------+ 677+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 678+-----------------------------------------------------------------------+ 679 680In 2.1 kernel and modules has moved to boot directory. For most cases 681this is handled automatically by 'make upgrade'. A few cases needs manual 682intervention: 683 684 * When installing a kernel without first doing a make buildworld, 685 installworld and upgrade to the same DESTDIR as kernel: 686 make DESTDIR/boot directory and move kernel and modules into this boot 687 directory; also move kernel.old and modules.old. 688 Typical example is vkernel(7), use (no modules used): 689 690 cd /var/vkernel 691 mkdir boot 692 chflags noschg kernel 693 mv kernel kernel.old boot 694 chflags schg boot/kernel 695 696 * When using a boot-only partition, /boot/loader.rc needs to be edited: 697 delete occurrences of '/boot/'. 698 These occurences can normally be deleted in any case, see loader(8). 699 700+-----------------------------------------------------------------------+ 701+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 702+-----------------------------------------------------------------------+ 703 704In 1.9 major changes to the disk management infrastructure have taken 705place. make upgrade may not catch all of your disk devices in /dev, 706so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 707are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 708and MAKEDEV no longer exists. 709 710The biggest changes in 1.9 are: 711 712(1) That whole-slice devices such as da0s1 no longer share the same device 713 id as partition c devices such as da0s1c. 714 715(2) The whole-disk device (e.g. da0) is full raw access to the disk, 716 with no snooping or reserved sectors. Consequently you cannot run 717 disklabel on this device. Instead you must run disklabel on a 718 whole-slice device. 719 720(3) The 'compatibility' partitions now use slice 0 in the device name, 721 so instead of da0a you must specify da0s0a. Also, as per (1) above, 722 accessing the disklabel for the compatibility partitions must be 723 done via slice 0 (da0s0). 724 725(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 726 and CCD now run through the disk management layer and are assigned 727 real disk management devices. VN and CCD in particular do not usually 728 use a MBR and disklabels must be accessed through the compatibility 729 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 730 don't name it 'ccd0s0' in the config file. 731 732Generally speaking, you have to get used to running fdisk and disklabel on 733the correctly specified device names. A lot of the wiggle, such as running 734disklabel on a partition, has been removed. 735 736+-----------------------------------------------------------------------+ 737+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 738+-----------------------------------------------------------------------+ 739 740> Kerberos IV 741------------- 742 743Kerberos IV (eBones) was removed from the tree, please consider moving to 744Kerberos 5 (Heimdal). 745 746> Package Management System 747--------------------------- 748 749Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 750management system. The necessary tools to build and maintain packages 751are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 752directories are in your PATH variable. 753 754In order to obtain a reasonably current snapshot of the pkgsrc tree, use 755the tarball from NetBSD: 756 757 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 758 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 759 760This tree can then be kept up to date with cvs update: 761 762 cd /usr/pkgsrc; cvs up 763 764NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 765build and install the pkgsrc bootstrap manually: 766 767 cd /usr/pkgsrc/bootstrap 768 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 769 770+-----------------------------------------------------------------------+ 771+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 772+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 773+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 774+-----------------------------------------------------------------------+ 775 776The compatibility shims for the build environment have been removed, you 777have to update to DragonFly 1.2 release branch first. 778 779The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 780The existing configuration can be converted using /etc/pam.d/convert.sh. 781Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 782the pam_skey.so module was retired, you have to remove it manually from 783your configuration, when you convert it. 784 785> Required user and group IDs when upgrading from either FreeBSD or DragonFly 786--------------------- 787 788The following users may be missing from your password file. Use vipw and 789add any that are missing: 790 791smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 792_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 793 794The following groups may be missing from your group file. Use vi /etc/group 795and add any that are missing: 796 797smmsp:*:25: 798authpf:*:63: 799_pflogd:*:64: 800 801 802> Upgrading to DragonFly from FreeBSD 803--------------------- 804 805You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 806FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 807FreeBSD. Note that the DragonFly buildworld target does not try to reuse 808make depend information, it starts from scratch, so no pre-cleaning of the 809object hierarchy is necessary. 810 811 # get the CVS repository (it is placed in /home/dcvs, 500MB). 812 # Please use the -h option and a mirror site to pull the 813 # initial repository, but feel free to use the main repository 814 # machine to pull updates. 815 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 816 # install the source from the CVS hierarchy (remove preexisting 817 # FreeBSD src first) (500MB) 818 cd /usr 819 rm -rf src 820 cvs -R -d /home/dcvs checkout -P src 821 822 # build it (500MB used in /usr/obj) 823 # 824 cd /usr/src 825 make buildworld 826 make buildkernel KERNCONF=<KERNELNAME> 827 828Once you have built DragonFly you have to install it over FreeBSD. Since 829DragonFly does not track changes made by FreeBSD to its include file 830hierarchy and include file pollution can cause all sorts of unexpected 831compilation issues to come up, it is best to wipe your include hierarchy 832prior to installing DragonFly. Note that you should not wipe any installed 833FreeBSD header files or binaries until after you have successfully completed 834the build steps above. 835 836 rm -rf /usr/include 837 mkdir /usr/include 838 make installkernel KERNCONF=<KERNELNAME> 839 make installworld 840 841Then you need to upgrade your system. DragonFly's 'make upgrade' target 842will unconditionally upgrade the /etc files that sysops do not usually 843mess around with, such as the files in /etc/rc.d. It will also remove any 844obsolete files such as utilities and manpages that have been removed from 845the system since the version you're coming from. If you are unsure we 846recommend that you make a backup of at least your /etc before applying 847this step. Note that DragonFly's RC system is basically RCNG from 848FreeBSD-5, but there are some differences in the contents of the RC files. 849 850 make upgrade 851 852NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 853Doing so might leave your system in an unusable state. 854 855Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 856/usr/bin, and /usr/lib, and remove any stale files that you find. Please 857report these files to the DragonFly developers so that they can be added to 858the 'upgrade' target. 859 860
