28DSCHED REMOVED
29--------------
30
31dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was
32in our default kernel config file. So the DSCHED_FQ option has been turned
33into a no-op for now and can be removed from custom configurations.

35EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO
36-------------------------------------------------
37
38The est(4) driver has been removed. All CPUs it supported (except one)
39were 32 bits only. Those who are still using the Core 2 Duo T7500 should
40report back if there are any issues with this CPU and our regular ACPI
41P-state support.
42
43Also, compile_et(1) and com_err(3) have been removed as well. They
44should have been removed along with kerberos support, back in 2009.

76BINUTILS 2.25 REPLACES 2.22, PRIMARY
77------------------------------------
78
79The oldest of the two versions of Binutils, version 2.22, was removed
80and replaced with Binutils 2.25. It becomes the primary version version
81of binutils and version 2.24 becomes the alternate. There are 8 current
82CVE written against 2.24, so for security reasons version 2.25 should
83always be used.
84
85The accepted values of BINUTILSVER are now "binutils225" (default) and
86"binutils224". The building of Binutils 2.24 can be prevented by setting
87NO_ALTBINUTILS=yes in make.conf.

89LOADER OPTIONS CHANGED
90----------------------
91
92Right after the development branch started, the Fred art accompanying the
93loader menu was improved. The line between Fred and the menu was removed
94by default (but can optionally be returned) and the placement shifted as
95a result. The drawing was improved, and the colored version was improved,
96changing the eyes and wing color from white to red. A new color version
97of Fred was added, one with a blue scheme.
98
99The loader menu defaults have changed since release 4.0: The vertical
100line was removed, the loader is displayed in color by default*, and the
101blue scheme is used.
102
103The loader.conf changes are:
104loader_color: option has been removed
105loader_plain: option has been added, it changed menu to monochrome
106fred_is_red: changes color scheme from blue to red
107fred_is_blue: option existed only on 4.1, it has been removed
108fred_separated: Adds line between Fred and menu (as seen previously)
109
110* If loader.conf defines "console" as "comconsole" or "console" is defined
111 in the environment as "comconsole" then color will not be displayed,
112 even if loader_plain value is "NO".

114SENDMAIL REMOVED FROM BASE
115--------------------------
116
117The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
118If the system being upgraded is still configured to use the sendmail
119binaries from base, the "make upgrade" command will fail.
120
121The administrator must change /etc/mail/mailer.conf to switch the
122mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
123command that permanently removes sendmail executables and could
124potentially break a running mail server.
125
126Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
127detailed instructions on how to configure the MTA selection.

148OLD USB DRIVERS REMOVED
149-----------------------
150
151The old USB stack, along with the kernel config option "device oldusb"
152and the make.conf variable "WANT_OLDUSB" have been removed. This means
153that for custom kernel configuration files which were derived from a
154GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
155various (old USB stack specific) devices will now complain about being
156unknown:
157
158 * oldusb (obviously)
159 * natausb (not yet ported to usb4bsd)
160 * rue (not yet ported to usb4bsd)
161 * ugen (no longer needed in usb4bsd)
162 * urio (not yet ported to usb4bsd)
163 * uscanner (no longer needed in usb4bsd)
164
165They should be removed or commented out in such custom kernel configs.

167GCC 5
168-----
169
170The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
171The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
172NO_CXX. The latter was never documented and the latest versions of GCC are
173partially written in C++ so a C++ compiler is no longer optional. In
174practical terms it has not been optional for many years as other base
175components are also written in C++. The resource savings by avoiding
176building Objective-C compiler is so small, the complexity added by NO_OBJC
177internally was deemed a bad tradeoff so that is the reason for its removal.
178Also note that no "info" pages are installed with GCC 5. After this entry
179was originally written, all info pages were removed from DragonFly.
180
181GCC 5.1 has been designated as the primary compiler. As such, there is a
182new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
183the designated secondary compiler, GCC 4.7. However, while DPorts
184primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
185if building ports from source is desired, don't block building of the
186secondary compiler.

195DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
196the default now (even on single-core systems), both for, like, 21 months.
197We kept the options around as no-ops as a convenience, to allow people
198using the same config for the then current release and the then current
199master. That period is now over, so any configs still having those
200options have to be adjusted.

214
215http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html

224and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
225removed in kernel configs derived from X86_64_GENERIC.

320GCC 4.7
321-------
322
323DragonFly has switched base compilers. GCC 4.7 is now the default
324compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
325variable ceases to work now.
326
327Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
328/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
329highly discouraged. There are a few packages in pkgsrc that do not build
330with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
331this time, it is recommended to keep both compilers on the base system.

484GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
485been made DragonFly's default Binutils.
30c91f0c
SW
486
487That means that any settings that set CCVER to 'gcc44' are not needed
488anymore. Instead, CCVER can be set to 'gcc41' to go back to using
489GCC 4.1.
490
b1242318
SW
491It also means that 'binutils221' as a value for BINUTILSVER has no
492effect anymore. 2.17 has been removed and 'binutils220' is available
493as an option.
494
5738210d 495The NO_GCC44 option has been removed and will not affect the build
30c91f0c

496anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
497building in a similar fashion.
498

524A new loader (dloader) has been added which better handles booting from
525multiple kernel/module versions.
526
527To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
528
529 cd /usr/src
530 make buildworld
531 make installworld
532 make upgrade
533 make buildkernel KERNCONF=<KERNELNAME>
534 make installkernel KERNCONF=<KERNELNAME>

536Note that you must installworld and run the 'upgrade' target before
537installing the new kernel.

541
542BIND has been removed from the base system. The ldns and drill tools have
543been added for basic functionality. Use 'drill' where you would normally
544use nslookup or dig, or install BIND from pkgsrc. It's available as
545net/bind95, net/bind96, or net/bind97 as of this writing.
546
547This only affects older systems upgrading to 2.8. New 2.8+ installs
548include BIND as a pkgsrc package.

557
558To upgrade a DragonFly system from sources you run the following sequence:
559
560 cd /usr/src
561 make buildworld
562 make buildkernel KERNCONF=<KERNELNAME>
563 make installkernel KERNCONF=<KERNELNAME>
564 make installworld
565
566You will also want to run the 'upgrade' target to upgrade your /etc and the
567rest of your system. The upgrade target is aware of stale files created by
568older DragonFly installations and should delete them automatically.
569
570 make upgrade

572See the build(7) manual page for further information.
573
d2a0decc
MD
574Once you've done a full build of the world and kernel you can do incremental
575upgrades of either by using the 'quickworld' and 'quickkernel' targets
576instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 577the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 578and buildkernel as shown above, before asking for help.

583
584In 2.1 kernel and modules has moved to boot directory. For most cases
585this is handled automatically by 'make upgrade'. A few cases needs manual
586intervention:
587
588 * When installing a kernel without first doing a make buildworld,
589 installworld and upgrade to the same DESTDIR as kernel:
590 make DESTDIR/boot directory and move kernel and modules into this boot
591 directory; also move kernel.old and modules.old.
592 Typical example is vkernel(7), use (no modules used):
593
594 cd /var/vkernel
595 mkdir boot
596 chflags noschg kernel
597 mv kernel kernel.old boot
598 chflags schg boot/kernel
599
600 * When using a boot-only partition, /boot/loader.rc needs to be edited:
601 delete occurrences of '/boot/'.
602 These occurences can normally be deleted in any case, see loader(8).

607
608In 1.9 major changes to the disk management infrastructure have taken
609place. make upgrade may not catch all of your disk devices in /dev,
610so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
611are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
612and MAKEDEV no longer exists.
d2a0decc
MD
613
614The biggest changes in 1.9 are:
615
616(1) That whole-slice devices such as da0s1 no longer share the same device
617 id as partition c devices such as da0s1c.
618
619(2) The whole-disk device (e.g. da0) is full raw access to the disk,
620 with no snooping or reserved sectors. Consequently you cannot run
621 disklabel on this device. Instead you must run disklabel on a
622 whole-slice device.
623
624(3) The 'compatibility' partitions now use slice 0 in the device name,
625 so instead of da0a you must specify da0s0a. Also, as per (1) above,
626 accessing the disklabel for the compatibility partitions must be
627 done via slice 0 (da0s0).
628
629(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
630 and CCD now run through the disk management layer and are assigned
631 real disk management devices. VN and CCD in particular do not usually
632 use a MBR and disklabels must be accessed through the compatibility
633 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
634 don't name it 'ccd0s0' in the config file.
635
636Generally speaking, you have to get used to running fdisk and disklabel on
637the correctly specified device names. A lot of the wiggle, such as running
638disklabel on a partition, has been removed.

645-------------
646
647Kerberos IV (eBones) was removed from the tree, please consider moving to
648Kerberos 5 (Heimdal).
649
650> Package Management System
651---------------------------
652
653Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
654management system. The necessary tools to build and maintain packages
655are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
656directories are in your PATH variable.
657
658In order to obtain a reasonably current snapshot of the pkgsrc tree, use
659the tarball from NetBSD:
660
661 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
662 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
663
664This tree can then be kept up to date with cvs update:
665
666 cd /usr/pkgsrc; cvs up
667
668NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
669build and install the pkgsrc bootstrap manually:
670
671 cd /usr/pkgsrc/bootstrap
672 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

709You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
710FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
711FreeBSD. Note that the DragonFly buildworld target does not try to reuse
712make depend information, it starts from scratch, so no pre-cleaning of the
713object hierarchy is necessary.

732Once you have built DragonFly you have to install it over FreeBSD. Since
733DragonFly does not track changes made by FreeBSD to its include file
734hierarchy and include file pollution can cause all sorts of unexpected
735compilation issues to come up, it is best to wipe your include hierarchy
736prior to installing DragonFly. Note that you should not wipe any installed
737FreeBSD header files or binaries until after you have successfully completed
738the build steps above.

741 mkdir /usr/include
742 make installkernel KERNCONF=<KERNELNAME>
743 make installworld
fb12f484 744
b8cbf045 745Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 746will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
747mess around with, such as the files in /etc/rc.d. It will also remove any
748obsolete files such as utilities and manpages that have been removed from
749the system since the version you're coming from. If you are unsure we
750recommend that you make a backup of at least your /etc before applying
751this step. Note that DragonFly's RC system is basically RCNG from
752FreeBSD-5, but there are some differences in the contents of the RC files.

753
754 make upgrade
755
b8cbf045
SW
756NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
757Doing so might leave your system in an unusable state.
758
f419daca 759Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
760/usr/bin, and /usr/lib, and remove any stale files that you find. Please
761report these files to the DragonFly developers so that they can be added to
762the 'upgrade' target.
