50Various former kernel configuration options which had been no-ops for
51some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B,
52_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in

103and replaced with Binutils 2.27. It becomes the primary version version
104of binutils and version 2.25 becomes the alternate.
105
106The accepted values of BINUTILSVER are now "binutils227" (default) and

116OPENSSL REMOVED
117---------------
118
119OpenSSL has been removed from base and replaced with a private version of
120LibreSSL. The previously installed OpenSSL libraries, headers, and man
121pages will remain on the system unless the "make upgrade" command is
122specifically instructed to remove them. To do this, define
123REMOVE_OPENSSL_FILES for the upgrade command, e.g.
124"make upgrade REMOVE_OPENSSL_FILES=yes"
125

MD
12628-Oct-2016: openssl has been replaced by ressl. It is recommended that any
127stale OpenSSL files be removed to avoid configuration scripts from using
128the stale and potentially vulnerable version, but all binaries that are
129dynamically linked to the OpenSSL libraries should be rebuilt first to
130avoid breakage.

132OPENSSH HPN REMOVED
133-------------------
134
135It has become too cumbersome to maintain HPN patches in OpenSSH in base.
136To use OpenSSH in base remove HPN config, if you have added it.
137Check files below for HPN config, see a few lines below.
138 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config
139sshd(8) will fail to start if HPN config is used.
140
141NOTE: HPN config in sshd_config will prohibit remote access to host using ssh.
142
143HPN config:
144HPNDisabled
145HPNBufferSize
146TcpRcvBuf
147TcpRcvBufPoll
148NoneEnabled

152
153OpenSSH HPN is a patch set to OpenSSH providing higher performance under some
154circumstances, especially for networking.
155If HPN functionality is needed, install security/openssh from dports.

207were 32 bits only. Those who are still using the Core 2 Duo T7500 should
208report back if there are any issues with this CPU and our regular ACPI
209P-state support.
210
211Also, compile_et(1) and com_err(3) have been removed as well. They
212should have been removed along with kerberos support, back in 2009.

245------------------------------------

247The oldest of the two versions of Binutils, version 2.22, was removed
248and replaced with Binutils 2.25. It becomes the primary version version
249of binutils and version 2.24 becomes the alternate. There are 8 current
250CVE written against 2.24, so for security reasons version 2.25 should
251always be used.
252
253The accepted values of BINUTILSVER are now "binutils225" (default) and
254"binutils224". The building of Binutils 2.24 can be prevented by setting
255NO_ALTBINUTILS=yes in make.conf.

257LOADER OPTIONS CHANGED
258----------------------
259
260Right after the development branch started, the Fred art accompanying the
261loader menu was improved. The line between Fred and the menu was removed
262by default (but can optionally be returned) and the placement shifted as
263a result. The drawing was improved, and the colored version was improved,
264changing the eyes and wing color from white to red. A new color version
265of Fred was added, one with a blue scheme.
266
267The loader menu defaults have changed since release 4.0: The vertical
268line was removed, the loader is displayed in color by default*, and the
269blue scheme is used.
270
271The loader.conf changes are:
272loader_color: option has been removed
273loader_plain: option has been added, it changed menu to monochrome
274fred_is_red: changes color scheme from blue to red
275fred_is_blue: option existed only on 4.1, it has been removed
276fred_separated: Adds line between Fred and menu (as seen previously)
277
278* If loader.conf defines "console" as "comconsole" or "console" is defined
279 in the environment as "comconsole" then color will not be displayed,
280 even if loader_plain value is "NO".

282SENDMAIL REMOVED FROM BASE
283--------------------------
284
285The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
286If the system being upgraded is still configured to use the sendmail
287binaries from base, the "make upgrade" command will fail.
288
289The administrator must change /etc/mail/mailer.conf to switch the
290mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
291command that permanently removes sendmail executables and could
292potentially break a running mail server.
293
294Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
295detailed instructions on how to configure the MTA selection.

317-----------------------
318
319The old USB stack, along with the kernel config option "device oldusb"
320and the make.conf variable "WANT_OLDUSB" have been removed. This means
321that for custom kernel configuration files which were derived from a
322GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
323various (old USB stack specific) devices will now complain about being
324unknown:
325
326 * oldusb (obviously)
327 * natausb (not yet ported to usb4bsd)
328 * rue (not yet ported to usb4bsd)
329 * ugen (no longer needed in usb4bsd)
330 * urio (not yet ported to usb4bsd)
331 * uscanner (no longer needed in usb4bsd)

333They should be removed or commented out in such custom kernel configs.

335GCC 5
336-----
337
338The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
339The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
340NO_CXX. The latter was never documented and the latest versions of GCC are
341partially written in C++ so a C++ compiler is no longer optional. In
342practical terms it has not been optional for many years as other base
343components are also written in C++. The resource savings by avoiding
344building Objective-C compiler is so small, the complexity added by NO_OBJC
345internally was deemed a bad tradeoff so that is the reason for its removal.
346Also note that no "info" pages are installed with GCC 5. After this entry
347was originally written, all info pages were removed from DragonFly.
348
349GCC 5.1 has been designated as the primary compiler. As such, there is a
350new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
351the designated secondary compiler, GCC 4.7. However, while DPorts
352primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
353if building ports from source is desired, don't block building of the
354secondary compiler.

488GCC 4.7
489-------
490
491DragonFly has switched base compilers. GCC 4.7 is now the default
492compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
493variable ceases to work now.
494
495Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
496/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
497highly discouraged. There are a few packages in pkgsrc that do not build
498with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
499this time, it is recommended to keep both compilers on the base system.

731 make installkernel KERNCONF=<KERNELNAME>
732 make installworld

750+-----------------------------------------------------------------------+
751
752In 2.1 kernel and modules has moved to boot directory. For most cases
753this is handled automatically by 'make upgrade'. A few cases needs manual
754intervention:
755
756 * When installing a kernel without first doing a make buildworld,
757 installworld and upgrade to the same DESTDIR as kernel:
758 make DESTDIR/boot directory and move kernel and modules into this boot
759 directory; also move kernel.old and modules.old.
760 Typical example is vkernel(7), use (no modules used):
761
762 cd /var/vkernel
763 mkdir boot
764 chflags noschg kernel
765 mv kernel kernel.old boot
766 chflags schg boot/kernel
767
768 * When using a boot-only partition, /boot/loader.rc needs to be edited:
769 delete occurrences of '/boot/'.
770 These occurences can normally be deleted in any case, see loader(8).

775
776In 1.9 major changes to the disk management infrastructure have taken
777place. make upgrade may not catch all of your disk devices in /dev,
778so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
779are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
780and MAKEDEV no longer exists.
d2a0decc
MD
781
782The biggest changes in 1.9 are:
783
784(1) That whole-slice devices such as da0s1 no longer share the same device
785 id as partition c devices such as da0s1c.
786
787(2) The whole-disk device (e.g. da0) is full raw access to the disk,
788 with no snooping or reserved sectors. Consequently you cannot run
789 disklabel on this device. Instead you must run disklabel on a
790 whole-slice device.
791
792(3) The 'compatibility' partitions now use slice 0 in the device name,
793 so instead of da0a you must specify da0s0a. Also, as per (1) above,
794 accessing the disklabel for the compatibility partitions must be
795 done via slice 0 (da0s0).
796
797(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
798 and CCD now run through the disk management layer and are assigned
799 real disk management devices. VN and CCD in particular do not usually
800 use a MBR and disklabels must be accessed through the compatibility
801 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
802 don't name it 'ccd0s0' in the config file.
803
804Generally speaking, you have to get used to running fdisk and disklabel on
805the correctly specified device names. A lot of the wiggle, such as running
806disklabel on a partition, has been removed.

818> Package Management System
819---------------------------
820
821Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
822management system. The necessary tools to build and maintain packages
823are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
824directories are in your PATH variable.
825
826In order to obtain a reasonably current snapshot of the pkgsrc tree, use
827the tarball from NetBSD:
828
829 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
830 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
831
832This tree can then be kept up to date with cvs update:
833
834 cd /usr/pkgsrc; cvs up
835
836NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
837build and install the pkgsrc bootstrap manually:

900Once you have built DragonFly you have to install it over FreeBSD. Since
901DragonFly does not track changes made by FreeBSD to its include file
902hierarchy and include file pollution can cause all sorts of unexpected
903compilation issues to come up, it is best to wipe your include hierarchy
904prior to installing DragonFly. Note that you should not wipe any installed
905FreeBSD header files or binaries until after you have successfully completed
906the build steps above.

b8cbf045
SW
915mess around with, such as the files in /etc/rc.d. It will also remove any
916obsolete files such as utilities and manpages that have been removed from
917the system since the version you're coming from. If you are unsure we
918recommend that you make a backup of at least your /etc before applying
919this step. Note that DragonFly's RC system is basically RCNG from
920FreeBSD-5, but there are some differences in the contents of the RC files.

924NOTE! Never do a 'make upgrade' before 'make installworld' has been run.

928/usr/bin, and /usr/lib, and remove any stale files that you find. Please
929report these files to the DragonFly developers so that they can be added to
