12 + UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS +
13 +-----------------------------------------------------------------------+
18 Support for the SCTP protocol has been removed.
20 OLD USB DRIVERS REMOVED
21 -----------------------
23 The old USB stack, along with the kernel config option "device oldusb"
24 and the make.conf variable "WANT_OLDUSB" have been removed. This means
25 that for custom kernel configuration files which were derived from a
26 GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
27 various (old USB stack specific) devices will now complain about being
31 * natausb (not yet ported to usb4bsd)
32 * rue (not yet ported to usb4bsd)
33 * ugen (no longer needed in usb4bsd)
34 * urio (not yet ported to usb4bsd)
35 * uscanner (no longer needed in usb4bsd)
37 They should be removed or commented out in such custom kernel configs.
39 +-----------------------------------------------------------------------+
40 + UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS +
41 +-----------------------------------------------------------------------+
43 SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN
44 -------------------------------------------
46 DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
47 the default now (even on single-core systems), both for, like, 21 months.
48 We kept the options around as no-ops as a convenience, to allow people
49 using the same config for the then current release and the then current
50 master. That period is now over, so any configs still having those
51 options have to be adjusted.
53 SYSVIPC SYSCALLS MADE NON-OPTIONAL
54 ----------------------------------
56 The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is
57 now compiled in by default. The options are no-ops for now.
59 DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
60 --------------------------------------------------------------------
62 The default driver for those controllers is now mrsas(4) due to reports
63 of file system corruption using the mfi(4) driver. The whole issue (and
64 how to deal with potential problems when switching) was explained here:
66 http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html
68 A tunable is provided for letting those controllers still attach via
69 the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page).
71 OLDER NETWORK DRIVERS MOVED TO I386 ONLY
72 ----------------------------------------
74 The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
75 and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
76 removed in kernel configs derived from X86_64_GENERIC.
78 +-----------------------------------------------------------------------+
79 + UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS +
80 +-----------------------------------------------------------------------+
82 UPDATE FROM MOST RECENT 3.6
83 ---------------------------
85 Versions of 3.6 built before June 25th have a bug where installworld might
86 crash during installation of the new initrd. Upgrade to the latest version
87 of 3.6 before updating to 3.8 or later.
89 ATM, IPX, NCP AND NWFS SUPPORT DROPPED
90 --------------------------------------
92 Support for the IPX and NCP network protocols and for mouting NetWare
93 file systems has been dropped. Dito for ATM protocol support.
95 INITRD IMAGES NOW INSTALLED BY DEFAULT
96 --------------------------------------
98 An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz
100 Older images installed under the file name of initrd.img will be removed
101 automatically by the make upgrade process.
103 USB4BSD IS NOW THE DEFAULT USB STACK
104 ------------------------------------
106 To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and
107 replace "device usb" with "device oldusb" in the kernel configuration.
109 MORE ISA SUPPORT DROPPED
110 ------------------------
112 ISA support has been dropped from the following drivers: adv(4), an(4),
113 ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4),
114 si(4), sn(4), and stg(4).
116 +-----------------------------------------------------------------------+
117 + UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS +
118 +-----------------------------------------------------------------------+
123 Installed third-party software (dports) will have to be rebuilt after upgrade,
124 or reinstalled from binary packages.
126 UPDATING FROM 3.4 TO 3.6
127 ------------------------
129 This only applies for this specific upgrade due to locale changes; it is
130 not needed for upgrades after 3.6. Please update in this order:
139 See this mailing list post for details:
140 http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html
142 CYRIX OPTIONS REMOVED
143 ---------------------
145 The following Cyrix related options have been removed: CPU_BTB_EN,
146 CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER,
147 CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT,
148 CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS
150 ISA SUPPORT REMOVED FROM RP(4)
151 ------------------------------
153 ISA support has been removed from the rp(4) driver. It is now PCI only.
155 +-----------------------------------------------------------------------+
156 + UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS +
157 +-----------------------------------------------------------------------+
159 COMPAT_SUNOS OPTION REMOVED
160 ---------------------------
162 The COMPAT_SUNOS option has been removed. It was meant to provide binary
163 compatibility with SunOS 4.x for the sparc32 port of 4.4BSD.
165 ISA SOUND CARD SUPPORT REMOVED
166 ------------------------------
168 The following modules have been removed (all for ISA sound cards):
169 snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko
174 DragonFly has switched base compilers. GCC 4.7 is now the default
175 compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
176 variable ceases to work now.
178 Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
179 /etc/make.conf to prohibit GCC 4.4 from building. However, using it is
180 highly discouraged. There are a few packages in pkgsrc that do not build
181 with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
182 this time, it is recommended to keep both compilers on the base system.
187 The SMP kernel option has been made a no-op. All kernels now feature SMP
188 support. If you have 'options SMP' in your kernel config, you can as well
191 DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED
192 ---------------------------------------------------------------------------
194 The DEVICE_POLLING kernel option has been made a no-op and it has been
195 replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your
196 kernel config, you need to change it to IFPOLL_ENABLE.
198 Also, the KTR_POLLING kernel option has been removed, so it must be
199 removed from kernel configs that have it.
201 BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED
202 ---------------------------------------------------
204 The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
205 cards will no longer be detected.
207 The same has been done for Stallion multiport serial controllers. stli(4)
208 has been completely removed (along with the stlload(8) and stlstty(8)
209 utilities) and stl(4) was changed to support only PCI cards. Similarly,
210 ISA support was removed from cy(4) too. All these drivers are i386 only.
212 COMPAT_OLDISA OPTION GONE
213 -------------------------
215 The i386 specific COMPAT_OLDISA kernel option has been removed, since
216 nothing needs it anymore.
218 +-----------------------------------------------------------------------+
219 + UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS +
220 +-----------------------------------------------------------------------+
222 APIC_IO OPTION REMOVED
223 ----------------------
225 The APIC_IO kernel option is no longer accepted after having been without
226 effect for a while. The hw.ioapic_enable tunable now serves its purpose.
227 If you have 'options APIC_IO' in your kernel config, you'll have to
230 WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED
231 -----------------------------------------
233 The wdog framework is now compiled into our kernels by default, so the
234 options are no longer needed.
239 doscmd(1) has been removed. It was i386 only. The doscmd(1) specific
240 NO_X make.conf option was removed too.
245 GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
246 default compiler in base (default is still GCC 4.4).
248 Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
249 NO_GCC47 in /etc/make.conf.
254 A new USB stack (from FreeBSD) has been brought in. The following
255 modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
256 usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
259 It is not yet the default. To activate it, WANT_USB4BSD=yes has to
260 be put in make.conf and device "usb4bsd" (quotes needed) has to
261 replace device usb in the kernel config. After that, a full
262 build/install/upgrade cycle is needed.
264 Note that this is experimental and incomplete, but we are interested
265 in hearing about issues with it, of course.
267 ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER
268 ---------------------------------------------
270 ISA adapter support was dropped from the aic(4) driver.
272 +-----------------------------------------------------------------------+
273 + UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS +
274 +-----------------------------------------------------------------------+
276 SEVERAL ISA DRIVERS REMOVED
277 ---------------------------
279 The following ISA only drivers have been removed along with a couple of
280 associated userland tools:
296 tw(4) & xten(1) & xtend(8)
300 Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
301 config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
304 If buildkernel complains about any of these drivers, just remove them
305 from your kernel configuration.
309 Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted
310 values of BINUTILSVERS are now binutils221 and binutils222 (default).
312 BUILDWORLD/-KERNEL PARALLELIZATION WORK
313 ---------------------------------------
314 Due to changes in the way we build with more than one make job, you
315 will have to update install(1) and mkdir(1) prior to buildworld if you
316 want to build with 'make -j':
318 cd /usr/src/usr.bin/xinstall; make; make install; make clean
319 cd /usr/src/bin/mkdir; make; make install; make clean
323 dma(8) has been upgraded to v0.7 which no longer supports the
324 /etc/dma/virtusertable. Some of its functionality has been replaced
325 with the MASQUERADE keyword and the EMAIL environment variable (see
326 the dma(8) manual page).
328 +-----------------------------------------------------------------------+
329 + UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS +
330 +-----------------------------------------------------------------------+
332 GCC 4.4 & BINUTILS 2.21
333 -----------------------
335 GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
336 been made DragonFly's default Binutils.
338 That means that any settings that set CCVER to 'gcc44' are not needed
339 anymore. Instead, CCVER can be set to 'gcc41' to go back to using
342 It also means that 'binutils221' as a value for BINUTILSVER has no
343 effect anymore. 2.17 has been removed and 'binutils220' is available
346 The NO_GCC44 option has been removed and will not affect the build
347 anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
348 building in a similar fashion.
350 Note that you must do a full buildworld/buildkernel for upgrading.
355 The config file for pkg_radd has moved from /etc/settings.conf to
356 /etc/pkg_radd.conf. Save the contents of settings.conf before upgrading
357 if this is needed. This warning only applies if /etc/settings.conf
358 exists. pkg_radd will continue to work with defaults.
360 +-----------------------------------------------------------------------+
362 + UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD +
363 +-----------------------------------------------------------------------+
368 OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
369 This shouldn't break any 3rd-party software, but you'll need to recompile your
370 3rd-party software if you want it to link against the new version of OpenSSL.
375 A new loader (dloader) has been added which better handles booting from
376 multiple kernel/module versions.
378 To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
384 make buildkernel KERNCONF=<KERNELNAME>
385 make installkernel KERNCONF=<KERNELNAME>
387 Note that you must installworld and run the 'upgrade' target before
388 installing the new kernel.
393 BIND has been removed from the base system. The ldns and drill tools have
394 been added for basic functionality. Use 'drill' where you would normally
395 use nslookup or dig, or install BIND from pkgsrc. It's available as
396 net/bind95, net/bind96, or net/bind97 as of this writing.
398 This only affects older systems upgrading to 2.8. New 2.8+ installs
399 include BIND as a pkgsrc package.
401 +-----------------------------------------------------------------------+
402 + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM +
404 +-----------------------------------------------------------------------+
406 Instructions on how to obtain and maintain DragonFly source code using git
407 are in the development(7) manual page.
409 To upgrade a DragonFly system from sources you run the following sequence:
413 make buildkernel KERNCONF=<KERNELNAME>
414 make installkernel KERNCONF=<KERNELNAME>
417 You will also want to run the 'upgrade' target to upgrade your /etc and the
418 rest of your system. The upgrade target is aware of stale files created by
419 older DragonFly installations and should delete them automatically.
423 See the build(7) manual page for further information.
425 Once you've done a full build of the world and kernel you can do incremental
426 upgrades of either by using the 'quickworld' and 'quickkernel' targets
427 instead of 'buildworld' and 'buildkernel'. If you have any problems with
428 the quick targets, try updating your repo first, and then a full buildworld
429 and buildkernel as shown above, before asking for help.
431 +-----------------------------------------------------------------------+
432 + UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 +
433 +-----------------------------------------------------------------------+
435 In 2.1 kernel and modules has moved to boot directory. For most cases
436 this is handled automatically by 'make upgrade'. A few cases needs manual
439 * When installing a kernel without first doing a make buildworld,
440 installworld and upgrade to the same DESTDIR as kernel:
441 make DESTDIR/boot directory and move kernel and modules into this boot
442 directory; also move kernel.old and modules.old.
443 Typical example is vkernel(7), use (no modules used):
447 chflags noschg kernel
448 mv kernel kernel.old boot
449 chflags schg boot/kernel
451 * When using a boot-only partition, /boot/loader.rc needs to be edited:
452 delete occurrences of '/boot/'.
453 These occurences can normally be deleted in any case, see loader(8).
455 +-----------------------------------------------------------------------+
456 + UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
457 +-----------------------------------------------------------------------+
459 In 1.9 major changes to the disk management infrastructure have taken
460 place. make upgrade may not catch all of your disk devices in /dev,
461 so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
462 are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
463 and MAKEDEV no longer exists.
465 The biggest changes in 1.9 are:
467 (1) That whole-slice devices such as da0s1 no longer share the same device
468 id as partition c devices such as da0s1c.
470 (2) The whole-disk device (e.g. da0) is full raw access to the disk,
471 with no snooping or reserved sectors. Consequently you cannot run
472 disklabel on this device. Instead you must run disklabel on a
475 (3) The 'compatibility' partitions now use slice 0 in the device name,
476 so instead of da0a you must specify da0s0a. Also, as per (1) above,
477 accessing the disklabel for the compatibility partitions must be
478 done via slice 0 (da0s0).
480 (4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
481 and CCD now run through the disk management layer and are assigned
482 real disk management devices. VN and CCD in particular do not usually
483 use a MBR and disklabels must be accessed through the compatibility
484 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
485 don't name it 'ccd0s0' in the config file.
487 Generally speaking, you have to get used to running fdisk and disklabel on
488 the correctly specified device names. A lot of the wiggle, such as running
489 disklabel on a partition, has been removed.
491 +-----------------------------------------------------------------------+
492 + UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD +
493 +-----------------------------------------------------------------------+
498 Kerberos IV (eBones) was removed from the tree, please consider moving to
499 Kerberos 5 (Heimdal).
501 > Package Management System
502 ---------------------------
504 Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
505 management system. The necessary tools to build and maintain packages
506 are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
507 directories are in your PATH variable.
509 In order to obtain a reasonably current snapshot of the pkgsrc tree, use
510 the tarball from NetBSD:
512 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
513 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
515 This tree can then be kept up to date with cvs update:
517 cd /usr/pkgsrc; cvs up
519 NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
520 build and install the pkgsrc bootstrap manually:
522 cd /usr/pkgsrc/bootstrap
523 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg
525 +-----------------------------------------------------------------------+
526 + UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM +
527 + UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO +
528 + DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) +
529 +-----------------------------------------------------------------------+
531 The compatibility shims for the build environment have been removed, you
532 have to update to DragonFly 1.2 release branch first.
534 The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
535 The existing configuration can be converted using /etc/pam.d/convert.sh.
536 Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
537 the pam_skey.so module was retired, you have to remove it manually from
538 your configuration, when you convert it.
540 > Required user and group IDs when upgrading from either FreeBSD or DragonFly
541 ---------------------
543 The following users may be missing from your password file. Use vipw and
544 add any that are missing:
546 smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
547 _pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
549 The following groups may be missing from your group file. Use vi /etc/group
550 and add any that are missing:
557 > Upgrading to DragonFly from FreeBSD
558 ---------------------
560 You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
561 FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
562 FreeBSD. Note that the DragonFly buildworld target does not try to reuse
563 make depend information, it starts from scratch, so no pre-cleaning of the
564 object hierarchy is necessary.
566 # get the CVS repository (it is placed in /home/dcvs, 500MB).
567 # Please use the -h option and a mirror site to pull the
568 # initial repository, but feel free to use the main repository
569 # machine to pull updates.
570 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
571 # install the source from the CVS hierarchy (remove preexisting
572 # FreeBSD src first) (500MB)
575 cvs -R -d /home/dcvs checkout -P src
577 # build it (500MB used in /usr/obj)
581 make buildkernel KERNCONF=<KERNELNAME>
583 Once you have built DragonFly you have to install it over FreeBSD. Since
584 DragonFly does not track changes made by FreeBSD to its include file
585 hierarchy and include file pollution can cause all sorts of unexpected
586 compilation issues to come up, it is best to wipe your include hierarchy
587 prior to installing DragonFly. Note that you should not wipe any installed
588 FreeBSD header files or binaries until after you have successfully completed
589 the build steps above.
593 make installkernel KERNCONF=<KERNELNAME>
596 Then you need to upgrade your system. DragonFly's 'make upgrade' target
597 will unconditionally upgrade the /etc files that sysops do not usually
598 mess around with, such as the files in /etc/rc.d. It will also remove any
599 obsolete files such as utilities and manpages that have been removed from
600 the system since the version you're coming from. If you are unsure we
601 recommend that you make a backup of at least your /etc before applying
602 this step. Note that DragonFly's RC system is basically RCNG from
603 FreeBSD-5, but there are some differences in the contents of the RC files.
607 NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
608 Doing so might leave your system in an unusable state.
610 Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
611 /usr/bin, and /usr/lib, and remove any stale files that you find. Please
612 report these files to the DragonFly developers so that they can be added to
613 the 'upgrade' target.
