15IF_PPP AND PPPD REMOVED
16-----------------------
17
18It has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had
19already been removed from our default kernel configuration before 5.0,
20so only people with custom configurations based on earlier X86_64_GENERIC
21will have to remove it manually.

41They were all in our X86_64_GENERIC kernel configuration file, along with

53The oldest of the two versions of Binutils, version 2.24, was removed
54and replaced with Binutils 2.27. It becomes the primary version version
55of binutils and version 2.25 becomes the alternate.
56
57The accepted values of BINUTILSVER are now "binutils227" (default) and
58"binutils225". The building of Binutils 2.25 can be prevented by setting
59NO_ALTBINUTILS=yes in make.conf.

67OPENSSL REMOVED
68---------------
69
70OpenSSL has been removed from base and replaced with a private version of
71LibreSSL. The previously installed OpenSSL libraries, headers, and man
72pages will remain on the system unless the "make upgrade" command is
73specifically instructed to remove them. To do this, define
74REMOVE_OPENSSL_FILES for the upgrade command, e.g.
75"make upgrade REMOVE_OPENSSL_FILES=yes"
76

7728-Oct-2016: openssl has been replaced by ressl. It is recommended that any
78stale OpenSSL files be removed to avoid configuration scripts from using
79the stale and potentially vulnerable version, but all binaries that are
80dynamically linked to the OpenSSL libraries should be rebuilt first to
81avoid breakage.

83OPENSSH HPN REMOVED
84-------------------
85
86It has become too cumbersome to maintain HPN patches in OpenSSH in base.
87To use OpenSSH in base remove HPN config, if you have added it.
88Check files below for HPN config, see a few lines below.
89 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config
90sshd(8) will fail to start if HPN config is used.
91
92NOTE: HPN config in sshd_config will prohibit remote access to host using ssh.
93
94HPN config:
95HPNDisabled
96HPNBufferSize
97TcpRcvBuf
98TcpRcvBufPoll

103
104OpenSSH HPN is a patch set to OpenSSH providing higher performance under some
105circumstances, especially for networking.
106If HPN functionality is needed, install security/openssh from dports.

111The cs(4), ex(4) and vx(4) drivers have been removed. They were very
112old and its doubtful they ever worked properly in x86_64 but they were
113in X86_64_GENERIC, so custom configurations derived from it have to be
3a609f3d 114adjusted.

158were 32 bits only. Those who are still using the Core 2 Duo T7500 should
159report back if there are any issues with this CPU and our regular ACPI
160P-state support.
161
162Also, compile_et(1) and com_err(3) have been removed as well. They
163should have been removed along with kerberos support, back in 2009.

199and replaced with Binutils 2.25. It becomes the primary version version
200of binutils and version 2.24 becomes the alternate. There are 8 current
201CVE written against 2.24, so for security reasons version 2.25 should
202always be used.
203
204The accepted values of BINUTILSVER are now "binutils225" (default) and
205"binutils224". The building of Binutils 2.24 can be prevented by setting
206NO_ALTBINUTILS=yes in make.conf.

208LOADER OPTIONS CHANGED
209----------------------
210
211Right after the development branch started, the Fred art accompanying the
212loader menu was improved. The line between Fred and the menu was removed
213by default (but can optionally be returned) and the placement shifted as
214a result. The drawing was improved, and the colored version was improved,
215changing the eyes and wing color from white to red. A new color version
216of Fred was added, one with a blue scheme.
217
218The loader menu defaults have changed since release 4.0: The vertical
219line was removed, the loader is displayed in color by default*, and the
220blue scheme is used.
221
222The loader.conf changes are:
223loader_color: option has been removed
224loader_plain: option has been added, it changed menu to monochrome
225fred_is_red: changes color scheme from blue to red
226fred_is_blue: option existed only on 4.1, it has been removed
227fred_separated: Adds line between Fred and menu (as seen previously)
228
229* If loader.conf defines "console" as "comconsole" or "console" is defined
230 in the environment as "comconsole" then color will not be displayed,
231 even if loader_plain value is "NO".

233SENDMAIL REMOVED FROM BASE
234--------------------------
235
236The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
237If the system being upgraded is still configured to use the sendmail
238binaries from base, the "make upgrade" command will fail.
239
240The administrator must change /etc/mail/mailer.conf to switch the
241mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
242command that permanently removes sendmail executables and could
243potentially break a running mail server.
244
245Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
246detailed instructions on how to configure the MTA selection.

269
270The old USB stack, along with the kernel config option "device oldusb"
271and the make.conf variable "WANT_OLDUSB" have been removed. This means
272that for custom kernel configuration files which were derived from a
273GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
274various (old USB stack specific) devices will now complain about being
275unknown:
276
277 * oldusb (obviously)
278 * natausb (not yet ported to usb4bsd)
279 * rue (not yet ported to usb4bsd)
280 * ugen (no longer needed in usb4bsd)
281 * urio (not yet ported to usb4bsd)
282 * uscanner (no longer needed in usb4bsd)

284They should be removed or commented out in such custom kernel configs.

286GCC 5
287-----
288
289The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
290The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
291NO_CXX. The latter was never documented and the latest versions of GCC are
292partially written in C++ so a C++ compiler is no longer optional. In
293practical terms it has not been optional for many years as other base
294components are also written in C++. The resource savings by avoiding
295building Objective-C compiler is so small, the complexity added by NO_OBJC
296internally was deemed a bad tradeoff so that is the reason for its removal.
297Also note that no "info" pages are installed with GCC 5. After this entry
298was originally written, all info pages were removed from DragonFly.
299
300GCC 5.1 has been designated as the primary compiler. As such, there is a
301new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
302the designated secondary compiler, GCC 4.7. However, while DPorts
303primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
304if building ports from source is desired, don't block building of the
305secondary compiler.

316We kept the options around as no-ops as a convenience, to allow people
317using the same config for the then current release and the then current
318master. That period is now over, so any configs still having those
319options have to be adjusted.

439GCC 4.7
440-------
441
442DragonFly has switched base compilers. GCC 4.7 is now the default
443compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
444variable ceases to work now.
445
446Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
447/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
448highly discouraged. There are a few packages in pkgsrc that do not build
449with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
450this time, it is recommended to keep both compilers on the base system.

680 make buildworld
681 make buildkernel KERNCONF=<KERNELNAME>
682 make installkernel KERNCONF=<KERNELNAME>
683 make installworld
684
685You will also want to run the 'upgrade' target to upgrade your /etc and the
686rest of your system. The upgrade target is aware of stale files created by
687older DragonFly installations and should delete them automatically.

693Once you've done a full build of the world and kernel you can do incremental
694upgrades of either by using the 'quickworld' and 'quickkernel' targets
695instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 696the quick targets, try updating your repo first, and then a full buildworld

701+-----------------------------------------------------------------------+
702
703In 2.1 kernel and modules has moved to boot directory. For most cases
704this is handled automatically by 'make upgrade'. A few cases needs manual
705intervention:
706
707 * When installing a kernel without first doing a make buildworld,
708 installworld and upgrade to the same DESTDIR as kernel:
709 make DESTDIR/boot directory and move kernel and modules into this boot
710 directory; also move kernel.old and modules.old.
711 Typical example is vkernel(7), use (no modules used):
712
713 cd /var/vkernel
714 mkdir boot
715 chflags noschg kernel
716 mv kernel kernel.old boot
717 chflags schg boot/kernel
718
719 * When using a boot-only partition, /boot/loader.rc needs to be edited:
720 delete occurrences of '/boot/'.
721 These occurences can normally be deleted in any case, see loader(8).

725+-----------------------------------------------------------------------+
726
727In 1.9 major changes to the disk management infrastructure have taken
728place. make upgrade may not catch all of your disk devices in /dev,
729so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
730are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
731and MAKEDEV no longer exists.
d2a0decc
MD
732
733The biggest changes in 1.9 are:
734
735(1) That whole-slice devices such as da0s1 no longer share the same device
736 id as partition c devices such as da0s1c.
737
738(2) The whole-disk device (e.g. da0) is full raw access to the disk,
739 with no snooping or reserved sectors. Consequently you cannot run
740 disklabel on this device. Instead you must run disklabel on a
741 whole-slice device.
742
743(3) The 'compatibility' partitions now use slice 0 in the device name,
744 so instead of da0a you must specify da0s0a. Also, as per (1) above,
745 accessing the disklabel for the compatibility partitions must be
746 done via slice 0 (da0s0).
747
748(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
749 and CCD now run through the disk management layer and are assigned
750 real disk management devices. VN and CCD in particular do not usually
751 use a MBR and disklabels must be accessed through the compatibility
752 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
753 don't name it 'ccd0s0' in the config file.
754
755Generally speaking, you have to get used to running fdisk and disklabel on
756the correctly specified device names. A lot of the wiggle, such as running
757disklabel on a partition, has been removed.

768
769> Package Management System
770---------------------------
771
772Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
773management system. The necessary tools to build and maintain packages
774are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
775directories are in your PATH variable.
776
777In order to obtain a reasonably current snapshot of the pkgsrc tree, use
778the tarball from NetBSD:
779
780 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
781 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
782
783This tree can then be kept up to date with cvs update:
784
785 cd /usr/pkgsrc; cvs up
786
787NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
788build and install the pkgsrc bootstrap manually:
789
790 cd /usr/pkgsrc/bootstrap

828You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
829FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing

851Once you have built DragonFly you have to install it over FreeBSD. Since
852DragonFly does not track changes made by FreeBSD to its include file
853hierarchy and include file pollution can cause all sorts of unexpected
854compilation issues to come up, it is best to wipe your include hierarchy
855prior to installing DragonFly. Note that you should not wipe any installed
856FreeBSD header files or binaries until after you have successfully completed
857the build steps above.

f419daca 865will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
866mess around with, such as the files in /etc/rc.d. It will also remove any
867obsolete files such as utilities and manpages that have been removed from
868the system since the version you're coming from. If you are unsure we
869recommend that you make a backup of at least your /etc before applying
870this step. Note that DragonFly's RC system is basically RCNG from
871FreeBSD-5, but there are some differences in the contents of the RC files.

875NOTE! Never do a 'make upgrade' before 'make installworld' has been run.

b8cbf045

879/usr/bin, and /usr/lib, and remove any stale files that you find. Please
880report these files to the DragonFly developers so that they can be added to
