12+         UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS                +
13+-----------------------------------------------------------------------+
14
15OLDER NETWORK DRIVERS MOVED TO I386 ONLY
16----------------------------------------
17
18The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
19and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
20removed in kernel configs derived from X86_64_GENERIC.
21
22+-----------------------------------------------------------------------+
23+         UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS                +
24+-----------------------------------------------------------------------+
25
26ATM, IPX, NCP AND NWFS SUPPORT DROPPED
27--------------------------------------
28
29Support for the IPX and NCP network protocols and for mouting NetWare
30file systems has been dropped. Dito for ATM protocol support.
31
32INITRD IMAGES NOW INSTALLED BY DEFAULT
33--------------------------------------
34
35An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz
36
37Older images installed under the file name of initrd.img will be removed
38automatically by the make upgrade process.
39
40USB4BSD IS NOW THE DEFAULT USB STACK
41------------------------------------
42
43To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and
44replace "device usb" with "device oldusb" in the kernel configuration.
45
46MORE ISA SUPPORT DROPPED
47------------------------
48
49ISA support has been dropped from the following drivers: adv(4), an(4),
50ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4),
51si(4), sn(4), and stg(4).

54+         UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS                +
55+-----------------------------------------------------------------------+
56
57ABI CHANGE
58----------
59
60Installed third-party software (dports) will have to be rebuilt after upgrade,
61or reinstalled from binary packages.
62
63UPDATING FROM 3.4 TO 3.6
64------------------------
65
66This only applies for this specific upgrade due to locale changes; it is
67not needed for upgrades after 3.6.  Please update in this order:
68
69make buildworld
70make buildkernel
71make installworld
72make installkernel
73*reboot*
74make upgrade
75
76See this mailing list post for details:
77http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html
78
79CYRIX OPTIONS REMOVED
80---------------------
81
82The following Cyrix related options have been removed: CPU_BTB_EN,
83CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER,
84CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT,
85CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS
86
87ISA SUPPORT REMOVED FROM RP(4)
88------------------------------
89
90ISA support has been removed from the rp(4) driver. It is now PCI only.
91
92+-----------------------------------------------------------------------+
93+         UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS                +
94+-----------------------------------------------------------------------+
95
96COMPAT_SUNOS OPTION REMOVED
97---------------------------
98
99The COMPAT_SUNOS option has been removed. It was meant to provide binary
100compatibility with SunOS 4.x for the sparc32 port of 4.4BSD.
101
102ISA SOUND CARD SUPPORT REMOVED
103------------------------------
104
105The following modules have been removed (all for ISA sound cards):
106snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko
107
108GCC 4.7
109-------
110
111DragonFly has switched base compilers.  GCC 4.7 is now the default
112compiler and GCC 4.4 is the alternative compiler.  The "NO_GCC47" make
113variable ceases to work now.
114
115Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
116/etc/make.conf to prohibit GCC 4.4 from building.  However, using it is
117highly discouraged.  There are a few packages in pkgsrc that do not build
118with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default.  At
119this time, it is recommended to keep both compilers on the base system.
120
121SMP OPTION REMOVED
122------------------
123
124The SMP kernel option has been made a no-op. All kernels now feature SMP
125support. If you have 'options SMP' in your kernel config, you can as well
126remove it.
127
128DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED
129---------------------------------------------------------------------------
130
131The DEVICE_POLLING kernel option has been made a no-op and it has been
132replaced by IFPOLL_ENABLE.  If you have 'options DEVICE_POLLING' in your
133kernel config, you need to change it to IFPOLL_ENABLE.
134
135Also, the KTR_POLLING kernel option has been removed, so it must be
136removed from kernel configs that have it.
137
138BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED
139---------------------------------------------------
140
141The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
142cards will no longer be detected.
143
144The same has been done for Stallion multiport serial controllers. stli(4)
145has been completely removed (along with the stlload(8) and stlstty(8)
146utilities) and stl(4) was changed to support only PCI cards. Similarly,
147ISA support was removed from cy(4) too. All these drivers are i386 only.
148
149COMPAT_OLDISA OPTION GONE
150-------------------------
151
152The i386 specific COMPAT_OLDISA kernel option has been removed, since
153nothing needs it anymore.
154
155+-----------------------------------------------------------------------+
156+         UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS                +
157+-----------------------------------------------------------------------+
158
159APIC_IO OPTION REMOVED
160----------------------
161
162The APIC_IO kernel option is no longer accepted after having been without
163effect for a while. The hw.ioapic_enable tunable now serves its purpose.
164If you have 'options APIC_IO' in your kernel config, you'll have to
165remove it.
166
167WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED
168-----------------------------------------
169
170The wdog framework is now compiled into our kernels by default, so the
171options are no longer needed.
172
173DOSCMD(1) REMOVED
174-----------------
175
176doscmd(1) has been removed. It was i386 only. The doscmd(1) specific
177NO_X make.conf option was removed too.
178
179GCC 4.7
180-------
181
182GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
183default compiler in base (default is still GCC 4.4).
184
185Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
186NO_GCC47 in /etc/make.conf.
187
188USB4BSD
189-------
190
191A new USB stack (from FreeBSD) has been brought in. The following
192modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
193usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
194and uaudio.
195
196It is not yet the default. To activate it, WANT_USB4BSD=yes has to
197be put in make.conf and device "usb4bsd" (quotes needed) has to
198replace device usb in the kernel config. After that, a full
199build/install/upgrade cycle is needed.
200
201Note that this is experimental and incomplete, but we are interested
202in hearing about issues with it, of course.
203
204ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER
205---------------------------------------------
206
207ISA adapter support was dropped from the aic(4) driver.
208
209+-----------------------------------------------------------------------+
210+         UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS               +
211+-----------------------------------------------------------------------+
212
213SEVERAL ISA DRIVERS REMOVED
214---------------------------
215
216The following ISA only drivers have been removed along with a couple of
217associated userland tools:
218
219aha(4)
220asc(4) & sasc(1)
221ctx
222dgb(4)
223el(4)
224gpib
225gsc(4) & sgsc(1)
226ie(4)
227labpc(4)
228le(4)
229mse(4)
230rc(4)
231rdp(4)
232spigot
233tw(4) & xten(1) & xtend(8)
234wl(4) & wlconfig(8)
235wt(4)
236
237Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
238config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
239file.
240
241If buildkernel complains about any of these drivers, just remove them
242from your kernel configuration.
243
244BINUTILS 2.20
245-------------
246Binutils 2.20 has been removed in favor of Binutils 2.22.  The accepted
247values of BINUTILSVERS are now binutils221 and binutils222 (default).
248
249BUILDWORLD/-KERNEL PARALLELIZATION WORK
250---------------------------------------
251Due to changes in the way we build with more than one make job, you
252will have to update install(1) and mkdir(1) prior to buildworld if you
253want to build with 'make -j':
254
255cd /usr/src/usr.bin/xinstall; make; make install; make clean
256cd /usr/src/bin/mkdir; make; make install; make clean
257
258DMA(8) UPGRADE
259--------------
260dma(8) has been upgraded to v0.7 which no longer supports the
261/etc/dma/virtusertable. Some of its functionality has been replaced
262with the MASQUERADE keyword and the EMAIL environment variable (see
263the dma(8) manual page).
264
265+-----------------------------------------------------------------------+
266+         UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS                +
267+-----------------------------------------------------------------------+
268
269GCC 4.4 & BINUTILS 2.21
270-----------------------
271
272GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
273been made DragonFly's default Binutils.
274
275That means that any settings that set CCVER to 'gcc44' are not needed
276anymore. Instead, CCVER can be set to 'gcc41' to go back to using
277GCC 4.1.
278
279It also means that 'binutils221' as a value for BINUTILSVER has no
280effect anymore. 2.17 has been removed and 'binutils220' is available
281as an option.
282
283The NO_GCC44 option has been removed and will not affect the build
284anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
285building in a similar fashion.
286
287Note that you must do a full buildworld/buildkernel for upgrading.
288
289pkg_radd settings
290-----------------
291
292The config file for pkg_radd has moved from /etc/settings.conf to
293/etc/pkg_radd.conf.  Save the contents of settings.conf before upgrading
294if this is needed.  This warning only applies if /etc/settings.conf
295exists.  pkg_radd will continue to work with defaults.
296
297+-----------------------------------------------------------------------+
298+         20100927							+
299+         UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD			+
300+-----------------------------------------------------------------------+
301
302OpenSSL
303--------
304
305OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
306This shouldn't break any 3rd-party software, but you'll need to recompile your
3073rd-party software if you want it to link against the new version of OpenSSL.
308
309Loader
310-------
311
312A new loader (dloader) has been added which better handles booting from
313multiple kernel/module versions.
314
315To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
316
317	cd /usr/src
318	make buildworld
319	make installworld
320	make upgrade
321	make buildkernel KERNCONF=<KERNELNAME>
322	make installkernel KERNCONF=<KERNELNAME>
323
324Note that you must installworld and run the 'upgrade' target before
325installing the new kernel.
326
327BIND
328-----
329
330BIND has been removed from the base system.  The ldns and drill tools have
331been added for basic functionality.  Use 'drill' where you would normally
332use nslookup or dig, or install BIND from pkgsrc.  It's available as
333net/bind95, net/bind96, or net/bind97 as of this writing.
334
335This only affects older systems upgrading to 2.8.  New 2.8+ installs
336include BIND as a pkgsrc package.
337
338+-----------------------------------------------------------------------+
339+         UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM		+
340+				GENERAL					+
341+-----------------------------------------------------------------------+
342
343Instructions on how to obtain and maintain DragonFly source code using git
344are in the development(7) manual page.
345
346To upgrade a DragonFly system from sources you run the following sequence:
347
348	cd /usr/src
349	make buildworld
350	make buildkernel KERNCONF=<KERNELNAME>
351	make installkernel KERNCONF=<KERNELNAME>
352	make installworld
353
354You will also want to run the 'upgrade' target to upgrade your /etc and the
355rest of your system.  The upgrade target is aware of stale files created by
356older DragonFly installations and should delete them automatically.
357
358	make upgrade
359
360See the build(7) manual page for further information.
361
362Once you've done a full build of the world and kernel you can do incremental
363upgrades of either by using the 'quickworld' and 'quickkernel' targets
364instead of 'buildworld' and 'buildkernel'.  If you have any problems with
365the quick targets, try updating your repo first, and then a full buildworld
366and buildkernel as shown above, before asking for help.
367
368+-----------------------------------------------------------------------+
369+         UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1		+
370+-----------------------------------------------------------------------+
371
372In 2.1 kernel and modules has moved to boot directory.  For most cases
373this is handled automatically by 'make upgrade'.  A few cases needs manual
374intervention:
375
376 * When installing a kernel without first doing a make buildworld,
377   installworld and upgrade to the same DESTDIR as kernel:
378   make DESTDIR/boot directory and move kernel and modules into this boot
379   directory; also move kernel.old and modules.old.
380   Typical example is vkernel(7), use (no modules used):
381
382	cd /var/vkernel
383	mkdir boot
384	chflags noschg kernel
385	mv kernel kernel.old boot
386	chflags schg boot/kernel
387
388 * When using a boot-only partition, /boot/loader.rc needs to be edited:
389   delete occurrences of '/boot/'.
390   These occurences can normally be deleted in any case, see loader(8).
391
392+-----------------------------------------------------------------------+
393+         UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9		+
394+-----------------------------------------------------------------------+
395
396In 1.9 major changes to the disk management infrastructure have taken
397place.  make upgrade may not catch all of your disk devices in /dev,
398so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
399are all of your disk devices.  HOWEVER, from late 2.3 on we run devfs
400and MAKEDEV no longer exists.
401
402The biggest changes in 1.9 are:
403
404(1) That whole-slice devices such as da0s1 no longer share the same device
405    id as partition c devices such as da0s1c.
406
407(2) The whole-disk device (e.g. da0) is full raw access to the disk,
408    with no snooping or reserved sectors.  Consequently you cannot run
409    disklabel on this device.  Instead you must run disklabel on a
410    whole-slice device.
411
412(3) The 'compatibility' partitions now use slice 0 in the device name,
413    so instead of da0a you must specify da0s0a.  Also, as per (1) above,
414    accessing the disklabel for the compatibility partitions must be
415    done via slice 0 (da0s0).
416
417(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
418    and CCD now run through the disk management layer and are assigned
419    real disk management devices.   VN and CCD in particular do not usually
420    use a MBR and disklabels must be accessed through the compatibility
421    slice 0.  Your /etc/ccd.conf file still specifies 'ccd0', though, you
422    don't name it 'ccd0s0' in the config file.
423
424Generally speaking, you have to get used to running fdisk and disklabel on
425the correctly specified device names.  A lot of the wiggle, such as running
426disklabel on a partition, has been removed.
427
428+-----------------------------------------------------------------------+
429+         UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD		+
430+-----------------------------------------------------------------------+
431
432> Kerberos IV
433-------------
434
435Kerberos IV (eBones) was removed from the tree, please consider moving to
436Kerberos 5 (Heimdal).
437
438> Package Management System
439---------------------------
440
441Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
442management system.  The necessary tools to build and maintain packages
443are provided in /usr/pkg/bin and /usr/pkg/sbin.  Make sure that these
444directories are in your PATH variable.
445
446In order to obtain a reasonably current snapshot of the pkgsrc tree, use
447the tarball from NetBSD:
448
449	fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
450	cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
451
452This tree can then be kept up to date with cvs update:
453
454	cd /usr/pkgsrc; cvs up
455
456NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
457build and install the pkgsrc bootstrap manually:
458
459	cd /usr/pkgsrc/bootstrap
460	./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg
461
462+-----------------------------------------------------------------------+
463+         UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM		+
464+         UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO               +
465+         DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD)                       +
466+-----------------------------------------------------------------------+
467
468The compatibility shims for the build environment have been removed, you
469have to update to DragonFly 1.2 release branch first.
470
471The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
472The existing configuration can be converted using /etc/pam.d/convert.sh.
473Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
474the pam_skey.so module was retired, you have to remove it manually from
475your configuration, when you convert it.
476
477> Required user and group IDs when upgrading from either FreeBSD or DragonFly
478---------------------
479
480The following users may be missing from your password file.  Use vipw and
481add any that are missing:
482
483smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
484_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
485
486The following groups may be missing from your group file.  Use vi /etc/group
487and add any that are missing:
488
489smmsp:*:25:
490authpf:*:63:
491_pflogd:*:64:
492
493
494> Upgrading to DragonFly from FreeBSD
495---------------------
496
497You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
498FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
499FreeBSD.  Note that the DragonFly buildworld target does not try to reuse
500make depend information, it starts from scratch, so no pre-cleaning of the
501object hierarchy is necessary.
502
503	# get the CVS repository (it is placed in /home/dcvs, 500MB).
504	# Please use the -h option and a mirror site to pull the
505	# initial repository, but feel free to use the main repository
506	# machine to pull updates.
507	cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
508	# install the source from the CVS hierarchy (remove preexisting
509	# FreeBSD src first) (500MB)
510	cd /usr
511	rm -rf src
512	cvs -R -d /home/dcvs checkout -P src
513
514	# build it (500MB used in /usr/obj)
515	#
516	cd /usr/src
517	make buildworld
518	make buildkernel KERNCONF=<KERNELNAME>
519
520Once you have built DragonFly you have to install it over FreeBSD.  Since
521DragonFly does not track changes made by FreeBSD to its include file
522hierarchy and include file pollution can cause all sorts of unexpected
523compilation issues to come up, it is best to wipe your include hierarchy
524prior to installing DragonFly.  Note that you should not wipe any installed
525FreeBSD header files or binaries until after you have successfully completed
526the build steps above.
527
528	rm -rf /usr/include
529	mkdir /usr/include
530	make installkernel KERNCONF=<KERNELNAME>
531	make installworld
532
533Then you need to upgrade your system.  DragonFly's 'make upgrade' target
534will unconditionally upgrade the /etc files that sysops do not usually
535mess around with, such as the files in /etc/rc.d.  It will also remove any
536obsolete files such as utilities and manpages that have been removed from
537the system since the version you're coming from.  If you are unsure we
538recommend that you make a backup of at least your /etc before applying
539this step.  Note that DragonFly's RC system is basically RCNG from
540FreeBSD-5, but there are some differences in the contents of the RC files.

542	make upgrade
543
544NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
545Doing so might leave your system in an unusable state.
546
547Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
548/usr/bin, and /usr/lib, and remove any stale files that you find.  Please
549report these files to the DragonFly developers so that they can be added to
550the 'upgrade' target.
