18The cs(4), ex(4) and vx(4) drivers have been removed. They were very
19old and its doubtful they ever worked properly in x86_64 but they were
20in X86_64_GENERIC, so custom configurations derived from it have to be
3a609f3d 21adjusted.

57dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was
58in our default kernel config file. So the DSCHED_FQ option has been turned
59into a no-op for now and can be removed from custom configurations.

61EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO
62-------------------------------------------------
63
64The est(4) driver has been removed. All CPUs it supported (except one)
65were 32 bits only. Those who are still using the Core 2 Duo T7500 should
66report back if there are any issues with this CPU and our regular ACPI
67P-state support.
68
69Also, compile_et(1) and com_err(3) have been removed as well. They
70should have been removed along with kerberos support, back in 2009.

102BINUTILS 2.25 REPLACES 2.22, PRIMARY
103------------------------------------
104
105The oldest of the two versions of Binutils, version 2.22, was removed
106and replaced with Binutils 2.25. It becomes the primary version version
107of binutils and version 2.24 becomes the alternate. There are 8 current
108CVE written against 2.24, so for security reasons version 2.25 should
109always be used.
110
111The accepted values of BINUTILSVER are now "binutils225" (default) and
112"binutils224". The building of Binutils 2.24 can be prevented by setting
113NO_ALTBINUTILS=yes in make.conf.

115LOADER OPTIONS CHANGED
116----------------------
117
118Right after the development branch started, the Fred art accompanying the
119loader menu was improved. The line between Fred and the menu was removed
120by default (but can optionally be returned) and the placement shifted as
121a result. The drawing was improved, and the colored version was improved,
122changing the eyes and wing color from white to red. A new color version
123of Fred was added, one with a blue scheme.
124
125The loader menu defaults have changed since release 4.0: The vertical
126line was removed, the loader is displayed in color by default*, and the
127blue scheme is used.
128
129The loader.conf changes are:
130loader_color: option has been removed
131loader_plain: option has been added, it changed menu to monochrome
132fred_is_red: changes color scheme from blue to red
133fred_is_blue: option existed only on 4.1, it has been removed
134fred_separated: Adds line between Fred and menu (as seen previously)
135
136* If loader.conf defines "console" as "comconsole" or "console" is defined
137 in the environment as "comconsole" then color will not be displayed,
138 even if loader_plain value is "NO".

140SENDMAIL REMOVED FROM BASE
141--------------------------
142
143The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
144If the system being upgraded is still configured to use the sendmail
145binaries from base, the "make upgrade" command will fail.
146
147The administrator must change /etc/mail/mailer.conf to switch the
148mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
149command that permanently removes sendmail executables and could
150potentially break a running mail server.
151
152Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
153detailed instructions on how to configure the MTA selection.

174OLD USB DRIVERS REMOVED
175-----------------------
176
177The old USB stack, along with the kernel config option "device oldusb"
178and the make.conf variable "WANT_OLDUSB" have been removed. This means
179that for custom kernel configuration files which were derived from a
180GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
181various (old USB stack specific) devices will now complain about being
182unknown:
183
184 * oldusb (obviously)
185 * natausb (not yet ported to usb4bsd)
186 * rue (not yet ported to usb4bsd)
187 * ugen (no longer needed in usb4bsd)
188 * urio (not yet ported to usb4bsd)
189 * uscanner (no longer needed in usb4bsd)
190
191They should be removed or commented out in such custom kernel configs.

193GCC 5
194-----
195
196The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
197The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
198NO_CXX. The latter was never documented and the latest versions of GCC are
199partially written in C++ so a C++ compiler is no longer optional. In
200practical terms it has not been optional for many years as other base
201components are also written in C++. The resource savings by avoiding
202building Objective-C compiler is so small, the complexity added by NO_OBJC
203internally was deemed a bad tradeoff so that is the reason for its removal.
204Also note that no "info" pages are installed with GCC 5. After this entry
205was originally written, all info pages were removed from DragonFly.
206
207GCC 5.1 has been designated as the primary compiler. As such, there is a
208new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
209the designated secondary compiler, GCC 4.7. However, while DPorts
210primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
211if building ports from source is desired, don't block building of the
212secondary compiler.

220
221DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
222the default now (even on single-core systems), both for, like, 21 months.
223We kept the options around as no-ops as a convenience, to allow people
224using the same config for the then current release and the then current
225master. That period is now over, so any configs still having those
226options have to be adjusted.

234DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
235--------------------------------------------------------------------
236
237The default driver for those controllers is now mrsas(4) due to reports
238of file system corruption using the mfi(4) driver. The whole issue (and
239how to deal with potential problems when switching) was explained here:
240
241http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html
242
243A tunable is provided for letting those controllers still attach via
244the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page).

249The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
250and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
251removed in kernel configs derived from X86_64_GENERIC.

346GCC 4.7
347-------
348
349DragonFly has switched base compilers. GCC 4.7 is now the default
350compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
351variable ceases to work now.
352
353Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
354/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
355highly discouraged. There are a few packages in pkgsrc that do not build
356with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
357this time, it is recommended to keep both compilers on the base system.

433
434It is not yet the default. To activate it, WANT_USB4BSD=yes has to
c7200221

488---------------------------------------
489Due to changes in the way we build with more than one make job, you
490will have to update install(1) and mkdir(1) prior to buildworld if you
491want to build with 'make -j':
492
493cd /usr/src/usr.bin/xinstall; make; make install; make clean

500with the MASQUERADE keyword and the EMAIL environment variable (see

510GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
511been made DragonFly's default Binutils.
30c91f0c
SW
512
513That means that any settings that set CCVER to 'gcc44' are not needed
514anymore. Instead, CCVER can be set to 'gcc41' to go back to using
515GCC 4.1.
516
b1242318
SW
517It also means that 'binutils221' as a value for BINUTILSVER has no
518effect anymore. 2.17 has been removed and 'binutils220' is available
519as an option.
520
5738210d 521The NO_GCC44 option has been removed and will not affect the build

523building in a similar fashion.

552
553To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
554
555 cd /usr/src
556 make buildworld
557 make installworld
558 make upgrade
559 make buildkernel KERNCONF=<KERNELNAME>

568BIND has been removed from the base system. The ldns and drill tools have
569been added for basic functionality. Use 'drill' where you would normally
570use nslookup or dig, or install BIND from pkgsrc. It's available as
571net/bind95, net/bind96, or net/bind97 as of this writing.
572
573This only affects older systems upgrading to 2.8. New 2.8+ installs
574include BIND as a pkgsrc package.

584To upgrade a DragonFly system from sources you run the following sequence:
585
586 cd /usr/src
587 make buildworld
588 make buildkernel KERNCONF=<KERNELNAME>
589 make installkernel KERNCONF=<KERNELNAME>
590 make installworld
591
592You will also want to run the 'upgrade' target to upgrade your /etc and the
593rest of your system. The upgrade target is aware of stale files created by
594older DragonFly installations and should delete them automatically.
595
596 make upgrade

600Once you've done a full build of the world and kernel you can do incremental
601upgrades of either by using the 'quickworld' and 'quickkernel' targets
602instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 603the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 604and buildkernel as shown above, before asking for help.

609
610In 2.1 kernel and modules has moved to boot directory. For most cases
611this is handled automatically by 'make upgrade'. A few cases needs manual
612intervention:
613
614 * When installing a kernel without first doing a make buildworld,
615 installworld and upgrade to the same DESTDIR as kernel:
616 make DESTDIR/boot directory and move kernel and modules into this boot
617 directory; also move kernel.old and modules.old.
618 Typical example is vkernel(7), use (no modules used):
619
620 cd /var/vkernel
621 mkdir boot
622 chflags noschg kernel
623 mv kernel kernel.old boot
624 chflags schg boot/kernel
625
626 * When using a boot-only partition, /boot/loader.rc needs to be edited:
627 delete occurrences of '/boot/'.
628 These occurences can normally be deleted in any case, see loader(8).

633
634In 1.9 major changes to the disk management infrastructure have taken
635place. make upgrade may not catch all of your disk devices in /dev,
636so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
637are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
638and MAKEDEV no longer exists.
d2a0decc
MD
639
640The biggest changes in 1.9 are:
641
642(1) That whole-slice devices such as da0s1 no longer share the same device
643 id as partition c devices such as da0s1c.
644
645(2) The whole-disk device (e.g. da0) is full raw access to the disk,
646 with no snooping or reserved sectors. Consequently you cannot run
647 disklabel on this device. Instead you must run disklabel on a
648 whole-slice device.
649
650(3) The 'compatibility' partitions now use slice 0 in the device name,
651 so instead of da0a you must specify da0s0a. Also, as per (1) above,
652 accessing the disklabel for the compatibility partitions must be
653 done via slice 0 (da0s0).
654
655(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
656 and CCD now run through the disk management layer and are assigned
657 real disk management devices. VN and CCD in particular do not usually
658 use a MBR and disklabels must be accessed through the compatibility
659 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
660 don't name it 'ccd0s0' in the config file.
661
662Generally speaking, you have to get used to running fdisk and disklabel on
663the correctly specified device names. A lot of the wiggle, such as running
664disklabel on a partition, has been removed.

673Kerberos IV (eBones) was removed from the tree, please consider moving to
674Kerberos 5 (Heimdal).
675
676> Package Management System
677---------------------------
678
679Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
680management system. The necessary tools to build and maintain packages
681are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
682directories are in your PATH variable.
683
684In order to obtain a reasonably current snapshot of the pkgsrc tree, use
685the tarball from NetBSD:
686
687 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
688 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
689
690This tree can then be kept up to date with cvs update:
691
692 cd /usr/pkgsrc; cvs up
693
694NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
695build and install the pkgsrc bootstrap manually:
696
697 cd /usr/pkgsrc/bootstrap
698 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

735You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
736FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
737FreeBSD. Note that the DragonFly buildworld target does not try to reuse
738make depend information, it starts from scratch, so no pre-cleaning of the
739object hierarchy is necessary.

758Once you have built DragonFly you have to install it over FreeBSD. Since
759DragonFly does not track changes made by FreeBSD to its include file
760hierarchy and include file pollution can cause all sorts of unexpected
761compilation issues to come up, it is best to wipe your include hierarchy
762prior to installing DragonFly. Note that you should not wipe any installed
763FreeBSD header files or binaries until after you have successfully completed
764the build steps above.

fb12f484 770
b8cbf045 771Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 772will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
773mess around with, such as the files in /etc/rc.d. It will also remove any
774obsolete files such as utilities and manpages that have been removed from
775the system since the version you're coming from. If you are unsure we
776recommend that you make a backup of at least your /etc before applying
777this step. Note that DragonFly's RC system is basically RCNG from
778FreeBSD-5, but there are some differences in the contents of the RC files.

780 make upgrade
781

SW
782NOTE! Never do a 'make upgrade' before 'make installworld' has been run.

784
f419daca 785Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
786/usr/bin, and /usr/lib, and remove any stale files that you find. Please
787report these files to the DragonFly developers so that they can be added to
788the 'upgrade' target.
