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 15COMPAT_43 KERNEL OPTION REMOVED 16------------------------------- 17 18It was commented out in our default configs for several years now, but 19might still be present in custom configs created before Nov. 2011. 20 21OPENSSL REMOVED 22--------------- 23 24OpenSSL has been removed from base and replaced with a private version of 25LibreSSL. The previously installed OpenSSL libraries, headers, and man 26pages will remain on the system unless the "make upgrade" command is 27specifically instructed to remove them. To do this, define 28REMOVE_OPENSSL_FILES for the upgrade command, e.g. 29"make upgrade REMOVE_OPENSSL_FILES=yes" 30 3128-Oct-2016: openssl has been replaced by ressl. It is recommended that any 32stale OpenSSL files be removed to avoid configuration scripts from using 33the stale and potentially vulnerable version, but all binaries that are 34dynamically linked to the OpenSSL libraries should be rebuilt first to 35avoid breakage. 36 37CS, EX AND VX DRIVERS REMOVED 38----------------------------- 39 40The cs(4), ex(4) and vx(4) drivers have been removed. They were very 41old and its doubtful they ever worked properly in x86_64 but they were 42in X86_64_GENERIC, so custom configurations derived from it have to be 43adjusted. 44 45+-----------------------------------------------------------------------+ 46+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 47+-----------------------------------------------------------------------+ 48 49AMD REMOVED 50----------- 51 52The am-utils automounter suite has been removed. It stopped working 53at some point and was never fixed. autofs(5) and the associated 54userland has been brought in from FreeBSD and replaces it. 55 56AN DRIVER REMOVED 57----------------- 58 59The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 60config file, so any configurations derived from it have to be adjusted. 61 62/DEV/DRI GROUP CHANGED 63---------------------- 64 65The default group assigned to /dev/dri entries has been changed 66from 'wheel' to 'video' with the id of '44'. If you want to have 67access to the dri devices please add yourself to the video group 68with: 69 70# pw groupmod video -m $USER 71 72+-----------------------------------------------------------------------+ 73+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 74+-----------------------------------------------------------------------+ 75 76DSCHED REMOVED 77-------------- 78 79dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 80in our default kernel config file. So the DSCHED_FQ option has been turned 81into a no-op for now and can be removed from custom configurations. 82 83EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 84------------------------------------------------- 85 86The est(4) driver has been removed. All CPUs it supported (except one) 87were 32 bits only. Those who are still using the Core 2 Duo T7500 should 88report back if there are any issues with this CPU and our regular ACPI 89P-state support. 90 91Also, compile_et(1) and com_err(3) have been removed as well. They 92should have been removed along with kerberos support, back in 2009. 93 94SEVERAL LOCALES RENAMED 95----------------------- 96 97Several locales were using obsolete and misleading names, and thus have 98been adjusted to current standards. Any users of the following locales 99need to select alternates: 100 101DFLY 4.2 locale DFLY 4.4 alterative locale 102--------------- ------------------------------------ 103mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 104no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 105no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 106no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 107sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 108sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 109sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 110zh_CN.GBK zh_Hans_CN.GBK 111zh_CN.UTF-8 zh_Hans_CN.UTF-8 112zh_CN.eucCN zh_Hans_CN.eucCN 113zh_CN.GB2312 zh_Hans_CH.GB2312 114zh_CN.GB18030 zh_Hans_CH.GB18030 115zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 116zh_HK.UTF_8 zh_Hant_HK.UTF-8 117zh_TW.Big5 zh_Hant_TW.Big5 118zh_TW.UTF-8 zh_Hant_TW.UTF-8 119 120+-----------------------------------------------------------------------+ 121+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 122+-----------------------------------------------------------------------+ 123 124BINUTILS 2.25 REPLACES 2.22, PRIMARY 125------------------------------------ 126 127The oldest of the two versions of Binutils, version 2.22, was removed 128and replaced with Binutils 2.25. It becomes the primary version version 129of binutils and version 2.24 becomes the alternate. There are 8 current 130CVE written against 2.24, so for security reasons version 2.25 should 131always be used. 132 133The accepted values of BINUTILSVER are now "binutils225" (default) and 134"binutils224". The building of Binutils 2.24 can be prevented by setting 135NO_ALTBINUTILS=yes in make.conf. 136 137LOADER OPTIONS CHANGED 138---------------------- 139 140Right after the development branch started, the Fred art accompanying the 141loader menu was improved. The line between Fred and the menu was removed 142by default (but can optionally be returned) and the placement shifted as 143a result. The drawing was improved, and the colored version was improved, 144changing the eyes and wing color from white to red. A new color version 145of Fred was added, one with a blue scheme. 146 147The loader menu defaults have changed since release 4.0: The vertical 148line was removed, the loader is displayed in color by default*, and the 149blue scheme is used. 150 151The loader.conf changes are: 152loader_color: option has been removed 153loader_plain: option has been added, it changed menu to monochrome 154fred_is_red: changes color scheme from blue to red 155fred_is_blue: option existed only on 4.1, it has been removed 156fred_separated: Adds line between Fred and menu (as seen previously) 157 158* If loader.conf defines "console" as "comconsole" or "console" is defined 159 in the environment as "comconsole" then color will not be displayed, 160 even if loader_plain value is "NO". 161 162SENDMAIL REMOVED FROM BASE 163-------------------------- 164 165The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 166If the system being upgraded is still configured to use the sendmail 167binaries from base, the "make upgrade" command will fail. 168 169The administrator must change /etc/mail/mailer.conf to switch the 170mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 171command that permanently removes sendmail executables and could 172potentially break a running mail server. 173 174Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 175detailed instructions on how to configure the MTA selection. 176 177_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 178-------------------------------------------- 179 180The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 181no-ops. They can be removed from custom kernel configurations. 182 183SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 184-------------------------------------------- 185 186Many more sound devices may be detected. 187 188If the default device choosen isn't to your liking, setting the sysctl 189hw.snd.default_unit to a different number will change it. 190 191SCTP SUPPORT DROPPED 192-------------------- 193 194Support for the SCTP protocol has been removed. 195 196OLD USB DRIVERS REMOVED 197----------------------- 198 199The old USB stack, along with the kernel config option "device oldusb" 200and the make.conf variable "WANT_OLDUSB" have been removed. This means 201that for custom kernel configuration files which were derived from a 202GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 203various (old USB stack specific) devices will now complain about being 204unknown: 205 206 * oldusb (obviously) 207 * natausb (not yet ported to usb4bsd) 208 * rue (not yet ported to usb4bsd) 209 * ugen (no longer needed in usb4bsd) 210 * urio (not yet ported to usb4bsd) 211 * uscanner (no longer needed in usb4bsd) 212 213They should be removed or commented out in such custom kernel configs. 214 215GCC 5 216----- 217 218The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 219The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 220NO_CXX. The latter was never documented and the latest versions of GCC are 221partially written in C++ so a C++ compiler is no longer optional. In 222practical terms it has not been optional for many years as other base 223components are also written in C++. The resource savings by avoiding 224building Objective-C compiler is so small, the complexity added by NO_OBJC 225internally was deemed a bad tradeoff so that is the reason for its removal. 226Also note that no "info" pages are installed with GCC 5. After this entry 227was originally written, all info pages were removed from DragonFly. 228 229GCC 5.1 has been designated as the primary compiler. As such, there is a 230new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 231the designated secondary compiler, GCC 4.7. However, while DPorts 232primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 233if building ports from source is desired, don't block building of the 234secondary compiler. 235 236+-----------------------------------------------------------------------+ 237+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 238+-----------------------------------------------------------------------+ 239 240SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 241------------------------------------------- 242 243DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 244the default now (even on single-core systems), both for, like, 21 months. 245We kept the options around as no-ops as a convenience, to allow people 246using the same config for the then current release and the then current 247master. That period is now over, so any configs still having those 248options have to be adjusted. 249 250SYSVIPC SYSCALLS MADE NON-OPTIONAL 251---------------------------------- 252 253The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 254now compiled in by default. The options are no-ops for now. 255 256DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 257-------------------------------------------------------------------- 258 259The default driver for those controllers is now mrsas(4) due to reports 260of file system corruption using the mfi(4) driver. The whole issue (and 261how to deal with potential problems when switching) was explained here: 262 263http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 264 265A tunable is provided for letting those controllers still attach via 266the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 267 268OLDER NETWORK DRIVERS MOVED TO I386 ONLY 269---------------------------------------- 270 271The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 272and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 273removed in kernel configs derived from X86_64_GENERIC. 274 275+-----------------------------------------------------------------------+ 276+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 277+-----------------------------------------------------------------------+ 278 279UPDATE FROM MOST RECENT 3.6 280--------------------------- 281 282Versions of 3.6 built before June 25th have a bug where installworld might 283crash during installation of the new initrd. Upgrade to the latest version 284of 3.6 before updating to 3.8 or later. 285 286ATM, IPX, NCP AND NWFS SUPPORT DROPPED 287-------------------------------------- 288 289Support for the IPX and NCP network protocols and for mouting NetWare 290file systems has been dropped. Dito for ATM protocol support. 291 292INITRD IMAGES NOW INSTALLED BY DEFAULT 293-------------------------------------- 294 295An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 296 297Older images installed under the file name of initrd.img will be removed 298automatically by the make upgrade process. 299 300USB4BSD IS NOW THE DEFAULT USB STACK 301------------------------------------ 302 303To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 304replace "device usb" with "device oldusb" in the kernel configuration. 305 306MORE ISA SUPPORT DROPPED 307------------------------ 308 309ISA support has been dropped from the following drivers: adv(4), an(4), 310ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 311si(4), sn(4), and stg(4). 312 313+-----------------------------------------------------------------------+ 314+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 315+-----------------------------------------------------------------------+ 316 317ABI CHANGE 318---------- 319 320Installed third-party software (dports) will have to be rebuilt after upgrade, 321or reinstalled from binary packages. 322 323UPDATING FROM 3.4 TO 3.6 324------------------------ 325 326This only applies for this specific upgrade due to locale changes; it is 327not needed for upgrades after 3.6. Please update in this order: 328 329make buildworld 330make buildkernel 331make installworld 332make installkernel 333*reboot* 334make upgrade 335 336See this mailing list post for details: 337http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 338 339CYRIX OPTIONS REMOVED 340--------------------- 341 342The following Cyrix related options have been removed: CPU_BTB_EN, 343CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 344CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 345CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 346 347ISA SUPPORT REMOVED FROM RP(4) 348------------------------------ 349 350ISA support has been removed from the rp(4) driver. It is now PCI only. 351 352+-----------------------------------------------------------------------+ 353+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 354+-----------------------------------------------------------------------+ 355 356COMPAT_SUNOS OPTION REMOVED 357--------------------------- 358 359The COMPAT_SUNOS option has been removed. It was meant to provide binary 360compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 361 362ISA SOUND CARD SUPPORT REMOVED 363------------------------------ 364 365The following modules have been removed (all for ISA sound cards): 366snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 367 368GCC 4.7 369------- 370 371DragonFly has switched base compilers. GCC 4.7 is now the default 372compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 373variable ceases to work now. 374 375Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 376/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 377highly discouraged. There are a few packages in pkgsrc that do not build 378with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 379this time, it is recommended to keep both compilers on the base system. 380 381SMP OPTION REMOVED 382------------------ 383 384The SMP kernel option has been made a no-op. All kernels now feature SMP 385support. If you have 'options SMP' in your kernel config, you can as well 386remove it. 387 388DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 389--------------------------------------------------------------------------- 390 391The DEVICE_POLLING kernel option has been made a no-op and it has been 392replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 393kernel config, you need to change it to IFPOLL_ENABLE. 394 395Also, the KTR_POLLING kernel option has been removed, so it must be 396removed from kernel configs that have it. 397 398BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 399--------------------------------------------------- 400 401The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 402cards will no longer be detected. 403 404The same has been done for Stallion multiport serial controllers. stli(4) 405has been completely removed (along with the stlload(8) and stlstty(8) 406utilities) and stl(4) was changed to support only PCI cards. Similarly, 407ISA support was removed from cy(4) too. All these drivers are i386 only. 408 409COMPAT_OLDISA OPTION GONE 410------------------------- 411 412The i386 specific COMPAT_OLDISA kernel option has been removed, since 413nothing needs it anymore. 414 415+-----------------------------------------------------------------------+ 416+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 417+-----------------------------------------------------------------------+ 418 419APIC_IO OPTION REMOVED 420---------------------- 421 422The APIC_IO kernel option is no longer accepted after having been without 423effect for a while. The hw.ioapic_enable tunable now serves its purpose. 424If you have 'options APIC_IO' in your kernel config, you'll have to 425remove it. 426 427WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 428----------------------------------------- 429 430The wdog framework is now compiled into our kernels by default, so the 431options are no longer needed. 432 433DOSCMD(1) REMOVED 434----------------- 435 436doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 437NO_X make.conf option was removed too. 438 439GCC 4.7 440------- 441 442GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 443default compiler in base (default is still GCC 4.4). 444 445Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 446NO_GCC47 in /etc/make.conf. 447 448USB4BSD 449------- 450 451A new USB stack (from FreeBSD) has been brought in. The following 452modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 453usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 454and uaudio. 455 456It is not yet the default. To activate it, WANT_USB4BSD=yes has to 457be put in make.conf and device "usb4bsd" (quotes needed) has to 458replace device usb in the kernel config. After that, a full 459build/install/upgrade cycle is needed. 460 461Note that this is experimental and incomplete, but we are interested 462in hearing about issues with it, of course. 463 464ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 465--------------------------------------------- 466 467ISA adapter support was dropped from the aic(4) driver. 468 469+-----------------------------------------------------------------------+ 470+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 471+-----------------------------------------------------------------------+ 472 473SEVERAL ISA DRIVERS REMOVED 474--------------------------- 475 476The following ISA only drivers have been removed along with a couple of 477associated userland tools: 478 479aha(4) 480asc(4) & sasc(1) 481ctx 482dgb(4) 483el(4) 484gpib 485gsc(4) & sgsc(1) 486ie(4) 487labpc(4) 488le(4) 489mse(4) 490rc(4) 491rdp(4) 492spigot 493tw(4) & xten(1) & xtend(8) 494wl(4) & wlconfig(8) 495wt(4) 496 497Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 498config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 499file. 500 501If buildkernel complains about any of these drivers, just remove them 502from your kernel configuration. 503 504BINUTILS 2.20 505------------- 506Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 507values of BINUTILSVERS are now binutils221 and binutils222 (default). 508 509BUILDWORLD/-KERNEL PARALLELIZATION WORK 510--------------------------------------- 511Due to changes in the way we build with more than one make job, you 512will have to update install(1) and mkdir(1) prior to buildworld if you 513want to build with 'make -j': 514 515cd /usr/src/usr.bin/xinstall; make; make install; make clean 516cd /usr/src/bin/mkdir; make; make install; make clean 517 518DMA(8) UPGRADE 519-------------- 520dma(8) has been upgraded to v0.7 which no longer supports the 521/etc/dma/virtusertable. Some of its functionality has been replaced 522with the MASQUERADE keyword and the EMAIL environment variable (see 523the dma(8) manual page). 524 525+-----------------------------------------------------------------------+ 526+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 527+-----------------------------------------------------------------------+ 528 529GCC 4.4 & BINUTILS 2.21 530----------------------- 531 532GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 533been made DragonFly's default Binutils. 534 535That means that any settings that set CCVER to 'gcc44' are not needed 536anymore. Instead, CCVER can be set to 'gcc41' to go back to using 537GCC 4.1. 538 539It also means that 'binutils221' as a value for BINUTILSVER has no 540effect anymore. 2.17 has been removed and 'binutils220' is available 541as an option. 542 543The NO_GCC44 option has been removed and will not affect the build 544anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 545building in a similar fashion. 546 547Note that you must do a full buildworld/buildkernel for upgrading. 548 549pkg_radd settings 550----------------- 551 552The config file for pkg_radd has moved from /etc/settings.conf to 553/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 554if this is needed. This warning only applies if /etc/settings.conf 555exists. pkg_radd will continue to work with defaults. 556 557+-----------------------------------------------------------------------+ 558+ 20100927 + 559+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 560+-----------------------------------------------------------------------+ 561 562OpenSSL 563-------- 564 565OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 566This shouldn't break any 3rd-party software, but you'll need to recompile your 5673rd-party software if you want it to link against the new version of OpenSSL. 568 569Loader 570------- 571 572A new loader (dloader) has been added which better handles booting from 573multiple kernel/module versions. 574 575To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 576 577 cd /usr/src 578 make buildworld 579 make installworld 580 make upgrade 581 make buildkernel KERNCONF=<KERNELNAME> 582 make installkernel KERNCONF=<KERNELNAME> 583 584Note that you must installworld and run the 'upgrade' target before 585installing the new kernel. 586 587BIND 588----- 589 590BIND has been removed from the base system. The ldns and drill tools have 591been added for basic functionality. Use 'drill' where you would normally 592use nslookup or dig, or install BIND from pkgsrc. It's available as 593net/bind95, net/bind96, or net/bind97 as of this writing. 594 595This only affects older systems upgrading to 2.8. New 2.8+ installs 596include BIND as a pkgsrc package. 597 598+-----------------------------------------------------------------------+ 599+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 600+ GENERAL + 601+-----------------------------------------------------------------------+ 602 603Instructions on how to obtain and maintain DragonFly source code using git 604are in the development(7) manual page. 605 606To upgrade a DragonFly system from sources you run the following sequence: 607 608 cd /usr/src 609 make buildworld 610 make buildkernel KERNCONF=<KERNELNAME> 611 make installkernel KERNCONF=<KERNELNAME> 612 make installworld 613 614You will also want to run the 'upgrade' target to upgrade your /etc and the 615rest of your system. The upgrade target is aware of stale files created by 616older DragonFly installations and should delete them automatically. 617 618 make upgrade 619 620See the build(7) manual page for further information. 621 622Once you've done a full build of the world and kernel you can do incremental 623upgrades of either by using the 'quickworld' and 'quickkernel' targets 624instead of 'buildworld' and 'buildkernel'. If you have any problems with 625the quick targets, try updating your repo first, and then a full buildworld 626and buildkernel as shown above, before asking for help. 627 628+-----------------------------------------------------------------------+ 629+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 630+-----------------------------------------------------------------------+ 631 632In 2.1 kernel and modules has moved to boot directory. For most cases 633this is handled automatically by 'make upgrade'. A few cases needs manual 634intervention: 635 636 * When installing a kernel without first doing a make buildworld, 637 installworld and upgrade to the same DESTDIR as kernel: 638 make DESTDIR/boot directory and move kernel and modules into this boot 639 directory; also move kernel.old and modules.old. 640 Typical example is vkernel(7), use (no modules used): 641 642 cd /var/vkernel 643 mkdir boot 644 chflags noschg kernel 645 mv kernel kernel.old boot 646 chflags schg boot/kernel 647 648 * When using a boot-only partition, /boot/loader.rc needs to be edited: 649 delete occurrences of '/boot/'. 650 These occurences can normally be deleted in any case, see loader(8). 651 652+-----------------------------------------------------------------------+ 653+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 654+-----------------------------------------------------------------------+ 655 656In 1.9 major changes to the disk management infrastructure have taken 657place. make upgrade may not catch all of your disk devices in /dev, 658so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 659are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 660and MAKEDEV no longer exists. 661 662The biggest changes in 1.9 are: 663 664(1) That whole-slice devices such as da0s1 no longer share the same device 665 id as partition c devices such as da0s1c. 666 667(2) The whole-disk device (e.g. da0) is full raw access to the disk, 668 with no snooping or reserved sectors. Consequently you cannot run 669 disklabel on this device. Instead you must run disklabel on a 670 whole-slice device. 671 672(3) The 'compatibility' partitions now use slice 0 in the device name, 673 so instead of da0a you must specify da0s0a. Also, as per (1) above, 674 accessing the disklabel for the compatibility partitions must be 675 done via slice 0 (da0s0). 676 677(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 678 and CCD now run through the disk management layer and are assigned 679 real disk management devices. VN and CCD in particular do not usually 680 use a MBR and disklabels must be accessed through the compatibility 681 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 682 don't name it 'ccd0s0' in the config file. 683 684Generally speaking, you have to get used to running fdisk and disklabel on 685the correctly specified device names. A lot of the wiggle, such as running 686disklabel on a partition, has been removed. 687 688+-----------------------------------------------------------------------+ 689+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 690+-----------------------------------------------------------------------+ 691 692> Kerberos IV 693------------- 694 695Kerberos IV (eBones) was removed from the tree, please consider moving to 696Kerberos 5 (Heimdal). 697 698> Package Management System 699--------------------------- 700 701Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 702management system. The necessary tools to build and maintain packages 703are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 704directories are in your PATH variable. 705 706In order to obtain a reasonably current snapshot of the pkgsrc tree, use 707the tarball from NetBSD: 708 709 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 710 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 711 712This tree can then be kept up to date with cvs update: 713 714 cd /usr/pkgsrc; cvs up 715 716NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 717build and install the pkgsrc bootstrap manually: 718 719 cd /usr/pkgsrc/bootstrap 720 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 721 722+-----------------------------------------------------------------------+ 723+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 724+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 725+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 726+-----------------------------------------------------------------------+ 727 728The compatibility shims for the build environment have been removed, you 729have to update to DragonFly 1.2 release branch first. 730 731The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 732The existing configuration can be converted using /etc/pam.d/convert.sh. 733Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 734the pam_skey.so module was retired, you have to remove it manually from 735your configuration, when you convert it. 736 737> Required user and group IDs when upgrading from either FreeBSD or DragonFly 738--------------------- 739 740The following users may be missing from your password file. Use vipw and 741add any that are missing: 742 743smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 744_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 745 746The following groups may be missing from your group file. Use vi /etc/group 747and add any that are missing: 748 749smmsp:*:25: 750authpf:*:63: 751_pflogd:*:64: 752 753 754> Upgrading to DragonFly from FreeBSD 755--------------------- 756 757You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 758FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 759FreeBSD. Note that the DragonFly buildworld target does not try to reuse 760make depend information, it starts from scratch, so no pre-cleaning of the 761object hierarchy is necessary. 762 763 # get the CVS repository (it is placed in /home/dcvs, 500MB). 764 # Please use the -h option and a mirror site to pull the 765 # initial repository, but feel free to use the main repository 766 # machine to pull updates. 767 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 768 # install the source from the CVS hierarchy (remove preexisting 769 # FreeBSD src first) (500MB) 770 cd /usr 771 rm -rf src 772 cvs -R -d /home/dcvs checkout -P src 773 774 # build it (500MB used in /usr/obj) 775 # 776 cd /usr/src 777 make buildworld 778 make buildkernel KERNCONF=<KERNELNAME> 779 780Once you have built DragonFly you have to install it over FreeBSD. Since 781DragonFly does not track changes made by FreeBSD to its include file 782hierarchy and include file pollution can cause all sorts of unexpected 783compilation issues to come up, it is best to wipe your include hierarchy 784prior to installing DragonFly. Note that you should not wipe any installed 785FreeBSD header files or binaries until after you have successfully completed 786the build steps above. 787 788 rm -rf /usr/include 789 mkdir /usr/include 790 make installkernel KERNCONF=<KERNELNAME> 791 make installworld 792 793Then you need to upgrade your system. DragonFly's 'make upgrade' target 794will unconditionally upgrade the /etc files that sysops do not usually 795mess around with, such as the files in /etc/rc.d. It will also remove any 796obsolete files such as utilities and manpages that have been removed from 797the system since the version you're coming from. If you are unsure we 798recommend that you make a backup of at least your /etc before applying 799this step. Note that DragonFly's RC system is basically RCNG from 800FreeBSD-5, but there are some differences in the contents of the RC files. 801 802 make upgrade 803 804NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 805Doing so might leave your system in an unusable state. 806 807Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 808/usr/bin, and /usr/lib, and remove any stale files that you find. Please 809report these files to the DragonFly developers so that they can be added to 810the 'upgrade' target. 811 812
