38dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was
39in our default kernel config file. So the DSCHED_FQ option has been turned
40into a no-op for now and can be removed from custom configurations.

42EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO

45The est(4) driver has been removed. All CPUs it supported (except one)
46were 32 bits only. Those who are still using the Core 2 Duo T7500 should
47report back if there are any issues with this CPU and our regular ACPI
48P-state support.
49
50Also, compile_et(1) and com_err(3) have been removed as well. They
51should have been removed along with kerberos support, back in 2009.

83BINUTILS 2.25 REPLACES 2.22, PRIMARY
84------------------------------------
85
86The oldest of the two versions of Binutils, version 2.22, was removed
87and replaced with Binutils 2.25. It becomes the primary version version
88of binutils and version 2.24 becomes the alternate. There are 8 current
89CVE written against 2.24, so for security reasons version 2.25 should
90always be used.
91
92The accepted values of BINUTILSVER are now "binutils225" (default) and
93"binutils224". The building of Binutils 2.24 can be prevented by setting
94NO_ALTBINUTILS=yes in make.conf.

96LOADER OPTIONS CHANGED
97----------------------
98
99Right after the development branch started, the Fred art accompanying the
100loader menu was improved. The line between Fred and the menu was removed
101by default (but can optionally be returned) and the placement shifted as
102a result. The drawing was improved, and the colored version was improved,
103changing the eyes and wing color from white to red. A new color version
104of Fred was added, one with a blue scheme.
105
106The loader menu defaults have changed since release 4.0: The vertical
107line was removed, the loader is displayed in color by default*, and the
108blue scheme is used.
109
110The loader.conf changes are:
111loader_color: option has been removed
112loader_plain: option has been added, it changed menu to monochrome
113fred_is_red: changes color scheme from blue to red
114fred_is_blue: option existed only on 4.1, it has been removed
115fred_separated: Adds line between Fred and menu (as seen previously)
116
117* If loader.conf defines "console" as "comconsole" or "console" is defined
118 in the environment as "comconsole" then color will not be displayed,
119 even if loader_plain value is "NO".

121SENDMAIL REMOVED FROM BASE
122--------------------------
123
124The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
125If the system being upgraded is still configured to use the sendmail
126binaries from base, the "make upgrade" command will fail.
127
128The administrator must change /etc/mail/mailer.conf to switch the
129mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
130command that permanently removes sendmail executables and could
131potentially break a running mail server.
132
133Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
134detailed instructions on how to configure the MTA selection.

155OLD USB DRIVERS REMOVED
156-----------------------
157
158The old USB stack, along with the kernel config option "device oldusb"
159and the make.conf variable "WANT_OLDUSB" have been removed. This means
160that for custom kernel configuration files which were derived from a
161GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
162various (old USB stack specific) devices will now complain about being
163unknown:
164
165 * oldusb (obviously)
166 * natausb (not yet ported to usb4bsd)
167 * rue (not yet ported to usb4bsd)
168 * ugen (no longer needed in usb4bsd)
169 * urio (not yet ported to usb4bsd)
170 * uscanner (no longer needed in usb4bsd)
171
172They should be removed or commented out in such custom kernel configs.

174GCC 5
175-----
176
177The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
178The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
179NO_CXX. The latter was never documented and the latest versions of GCC are
180partially written in C++ so a C++ compiler is no longer optional. In
181practical terms it has not been optional for many years as other base
182components are also written in C++. The resource savings by avoiding
183building Objective-C compiler is so small, the complexity added by NO_OBJC
184internally was deemed a bad tradeoff so that is the reason for its removal.
185Also note that no "info" pages are installed with GCC 5. After this entry
186was originally written, all info pages were removed from DragonFly.
187
188GCC 5.1 has been designated as the primary compiler. As such, there is a
189new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
190the designated secondary compiler, GCC 4.7. However, while DPorts
191primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
192if building ports from source is desired, don't block building of the
193secondary compiler.

202DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
203the default now (even on single-core systems), both for, like, 21 months.
204We kept the options around as no-ops as a convenience, to allow people
205using the same config for the then current release and the then current
206master. That period is now over, so any configs still having those
207options have to be adjusted.

215DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
216--------------------------------------------------------------------

218The default driver for those controllers is now mrsas(4) due to reports
219of file system corruption using the mfi(4) driver. The whole issue (and
220how to deal with potential problems when switching) was explained here:
221
222http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html
223
224A tunable is provided for letting those controllers still attach via
225the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page).

230The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
231and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
232removed in kernel configs derived from X86_64_GENERIC.

327GCC 4.7
328-------
329
330DragonFly has switched base compilers. GCC 4.7 is now the default
331compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
332variable ceases to work now.
333
334Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
335/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
336highly discouraged. There are a few packages in pkgsrc that do not build
337with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
338this time, it is recommended to keep both compilers on the base system.

492been made DragonFly's default Binutils.
30c91f0c

493
494That means that any settings that set CCVER to 'gcc44' are not needed
495anymore. Instead, CCVER can be set to 'gcc41' to go back to using
496GCC 4.1.
497
b1242318

498It also means that 'binutils221' as a value for BINUTILSVER has no
499effect anymore. 2.17 has been removed and 'binutils220' is available
500as an option.
501
5738210d 502The NO_GCC44 option has been removed and will not affect the build

540 make buildkernel KERNCONF=<KERNELNAME>

552net/bind95, net/bind96, or net/bind97 as of this writing.
553

565To upgrade a DragonFly system from sources you run the following sequence:
566
567 cd /usr/src
568 make buildworld
569 make buildkernel KERNCONF=<KERNELNAME>
570 make installkernel KERNCONF=<KERNELNAME>
571 make installworld
572
573You will also want to run the 'upgrade' target to upgrade your /etc and the
574rest of your system. The upgrade target is aware of stale files created by
575older DragonFly installations and should delete them automatically.
576
577 make upgrade

581Once you've done a full build of the world and kernel you can do incremental
582upgrades of either by using the 'quickworld' and 'quickkernel' targets
583instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 584the quick targets, try updating your repo first, and then a full buildworld

591In 2.1 kernel and modules has moved to boot directory. For most cases
592this is handled automatically by 'make upgrade'. A few cases needs manual
593intervention:
594
595 * When installing a kernel without first doing a make buildworld,
596 installworld and upgrade to the same DESTDIR as kernel:
597 make DESTDIR/boot directory and move kernel and modules into this boot
598 directory; also move kernel.old and modules.old.
599 Typical example is vkernel(7), use (no modules used):
600
601 cd /var/vkernel
602 mkdir boot
603 chflags noschg kernel
604 mv kernel kernel.old boot
605 chflags schg boot/kernel
606
607 * When using a boot-only partition, /boot/loader.rc needs to be edited:
608 delete occurrences of '/boot/'.
609 These occurences can normally be deleted in any case, see loader(8).

615In 1.9 major changes to the disk management infrastructure have taken
616place. make upgrade may not catch all of your disk devices in /dev,
617so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
618are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
619and MAKEDEV no longer exists.
d2a0decc
MD
620
621The biggest changes in 1.9 are:
622
623(1) That whole-slice devices such as da0s1 no longer share the same device
624 id as partition c devices such as da0s1c.
625
626(2) The whole-disk device (e.g. da0) is full raw access to the disk,
627 with no snooping or reserved sectors. Consequently you cannot run
628 disklabel on this device. Instead you must run disklabel on a
629 whole-slice device.
630
631(3) The 'compatibility' partitions now use slice 0 in the device name,
632 so instead of da0a you must specify da0s0a. Also, as per (1) above,
633 accessing the disklabel for the compatibility partitions must be
634 done via slice 0 (da0s0).
635
636(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
637 and CCD now run through the disk management layer and are assigned
638 real disk management devices. VN and CCD in particular do not usually
639 use a MBR and disklabels must be accessed through the compatibility
640 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
641 don't name it 'ccd0s0' in the config file.
642
643Generally speaking, you have to get used to running fdisk and disklabel on
644the correctly specified device names. A lot of the wiggle, such as running
645disklabel on a partition, has been removed.

654Kerberos IV (eBones) was removed from the tree, please consider moving to
655Kerberos 5 (Heimdal).
656
657> Package Management System
658---------------------------
659
660Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
661management system. The necessary tools to build and maintain packages
662are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
663directories are in your PATH variable.
664
665In order to obtain a reasonably current snapshot of the pkgsrc tree, use
666the tarball from NetBSD:
667
668 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
669 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
670
671This tree can then be kept up to date with cvs update:
672
673 cd /usr/pkgsrc; cvs up
674
675NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
676build and install the pkgsrc bootstrap manually:
677
678 cd /usr/pkgsrc/bootstrap

716You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
717FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
718FreeBSD. Note that the DragonFly buildworld target does not try to reuse
719make depend information, it starts from scratch, so no pre-cleaning of the
720object hierarchy is necessary.

739Once you have built DragonFly you have to install it over FreeBSD. Since
740DragonFly does not track changes made by FreeBSD to its include file
741hierarchy and include file pollution can cause all sorts of unexpected
742compilation issues to come up, it is best to wipe your include hierarchy
743prior to installing DragonFly. Note that you should not wipe any installed
744FreeBSD header files or binaries until after you have successfully completed
745the build steps above.

749 make installkernel KERNCONF=<KERNELNAME>
750 make installworld
fb12f484 751
b8cbf045 752Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 753will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
754mess around with, such as the files in /etc/rc.d. It will also remove any
755obsolete files such as utilities and manpages that have been removed from
756the system since the version you're coming from. If you are unsure we
757recommend that you make a backup of at least your /etc before applying
758this step. Note that DragonFly's RC system is basically RCNG from
759FreeBSD-5, but there are some differences in the contents of the RC files.

760
761 make upgrade
762
b8cbf045
SW
763NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
764Doing so might leave your system in an unusable state.
765
f419daca 766Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
767/usr/bin, and /usr/lib, and remove any stale files that you find. Please
768report these files to the DragonFly developers so that they can be added to
769the 'upgrade' target.
