32The FFS_ROOT kernel configuration option has been finally removed, after
33having been a no-op since 4.9. That means users using a custom kernel
34configuration file that still contains it need to remove the option from
35that file.

157OPENSSL REMOVED
158---------------
159
160OpenSSL has been removed from base and replaced with a private version of
161LibreSSL. The previously installed OpenSSL libraries, headers, and man
162pages will remain on the system unless the "make upgrade" command is
163specifically instructed to remove them. To do this, define
164REMOVE_OPENSSL_FILES for the upgrade command, e.g.
165"make upgrade REMOVE_OPENSSL_FILES=yes"

MD
16728-Oct-2016: openssl has been replaced by ressl. It is recommended that any
168stale OpenSSL files be removed to avoid configuration scripts from using
169the stale and potentially vulnerable version, but all binaries that are
170dynamically linked to the OpenSSL libraries should be rebuilt first to
171avoid breakage.

173OPENSSH HPN REMOVED

176It has become too cumbersome to maintain HPN patches in OpenSSH in base.
177To use OpenSSH in base remove HPN config, if you have added it.
178Check files below for HPN config, see a few lines below.
179 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config
180sshd(8) will fail to start if HPN config is used.
181
182NOTE: HPN config in sshd_config will prohibit remote access to host using ssh.
183

249report back if there are any issues with this CPU and our regular ACPI
250P-state support.

298LOADER OPTIONS CHANGED
299----------------------
300
301Right after the development branch started, the Fred art accompanying the
302loader menu was improved. The line between Fred and the menu was removed
303by default (but can optionally be returned) and the placement shifted as
304a result. The drawing was improved, and the colored version was improved,
305changing the eyes and wing color from white to red. A new color version
306of Fred was added, one with a blue scheme.
307
308The loader menu defaults have changed since release 4.0: The vertical
309line was removed, the loader is displayed in color by default*, and the
310blue scheme is used.
311
312The loader.conf changes are:
313loader_color: option has been removed
314loader_plain: option has been added, it changed menu to monochrome
315fred_is_red: changes color scheme from blue to red
316fred_is_blue: option existed only on 4.1, it has been removed
317fred_separated: Adds line between Fred and menu (as seen previously)
318
319* If loader.conf defines "console" as "comconsole" or "console" is defined
320 in the environment as "comconsole" then color will not be displayed,
321 even if loader_plain value is "NO".

323SENDMAIL REMOVED FROM BASE

326The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
327If the system being upgraded is still configured to use the sendmail
328binaries from base, the "make upgrade" command will fail.
329
330The administrator must change /etc/mail/mailer.conf to switch the
331mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
332command that permanently removes sendmail executables and could
333potentially break a running mail server.

362that for custom kernel configuration files which were derived from a
363GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
364various (old USB stack specific) devices will now complain about being
365unknown:

376GCC 5
377-----
378
379The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
380The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
381NO_CXX. The latter was never documented and the latest versions of GCC are
382partially written in C++ so a C++ compiler is no longer optional. In
383practical terms it has not been optional for many years as other base
384components are also written in C++. The resource savings by avoiding
385building Objective-C compiler is so small, the complexity added by NO_OBJC
386internally was deemed a bad tradeoff so that is the reason for its removal.
387Also note that no "info" pages are installed with GCC 5. After this entry
388was originally written, all info pages were removed from DragonFly.
389
390GCC 5.1 has been designated as the primary compiler. As such, there is a
391new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
392the designated secondary compiler, GCC 4.7. However, while DPorts
393primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
394if building ports from source is desired, don't block building of the
395secondary compiler.

529GCC 4.7
530-------
531
532DragonFly has switched base compilers. GCC 4.7 is now the default
533compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
534variable ceases to work now.
535
536Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
537/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
538highly discouraged. There are a few packages in pkgsrc that do not build
539with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
540this time, it is recommended to keep both compilers on the base system.

547remove it.

614usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
615and uaudio.
616
617It is not yet the default. To activate it, WANT_USB4BSD=yes has to
c7200221

618be put in make.conf and device "usb4bsd" (quotes needed) has to
619replace device usb in the kernel config. After that, a full

754net/bind95, net/bind96, or net/bind97 as of this writing.

767To upgrade a DragonFly system from sources you run the following sequence:

770 make buildworld
771 make buildkernel KERNCONF=<KERNELNAME>
772 make installkernel KERNCONF=<KERNELNAME>
773 make installworld
774
775You will also want to run the 'upgrade' target to upgrade your /etc and the
776rest of your system. The upgrade target is aware of stale files created by
777older DragonFly installations and should delete them automatically.
778
779 make upgrade

783Once you've done a full build of the world and kernel you can do incremental
784upgrades of either by using the 'quickworld' and 'quickkernel' targets
785instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 786the quick targets, try updating your repo first, and then a full buildworld

791+-----------------------------------------------------------------------+
792
793In 2.1 kernel and modules has moved to boot directory. For most cases
794this is handled automatically by 'make upgrade'. A few cases needs manual
795intervention:
796
797 * When installing a kernel without first doing a make buildworld,
798 installworld and upgrade to the same DESTDIR as kernel:
799 make DESTDIR/boot directory and move kernel and modules into this boot
800 directory; also move kernel.old and modules.old.
801 Typical example is vkernel(7), use (no modules used):
802
803 cd /var/vkernel
804 mkdir boot
805 chflags noschg kernel
806 mv kernel kernel.old boot
807 chflags schg boot/kernel
808
809 * When using a boot-only partition, /boot/loader.rc needs to be edited:
810 delete occurrences of '/boot/'.
811 These occurences can normally be deleted in any case, see loader(8).

815+-----------------------------------------------------------------------+
816
817In 1.9 major changes to the disk management infrastructure have taken
818place. make upgrade may not catch all of your disk devices in /dev,
819so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
820are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
821and MAKEDEV no longer exists.
d2a0decc
MD
822
823The biggest changes in 1.9 are:
824
825(1) That whole-slice devices such as da0s1 no longer share the same device
826 id as partition c devices such as da0s1c.
827
828(2) The whole-disk device (e.g. da0) is full raw access to the disk,
829 with no snooping or reserved sectors. Consequently you cannot run
830 disklabel on this device. Instead you must run disklabel on a
831 whole-slice device.
832
833(3) The 'compatibility' partitions now use slice 0 in the device name,
834 so instead of da0a you must specify da0s0a. Also, as per (1) above,
835 accessing the disklabel for the compatibility partitions must be
836 done via slice 0 (da0s0).
837
838(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
839 and CCD now run through the disk management layer and are assigned
840 real disk management devices. VN and CCD in particular do not usually
841 use a MBR and disklabels must be accessed through the compatibility
842 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
843 don't name it 'ccd0s0' in the config file.
844
845Generally speaking, you have to get used to running fdisk and disklabel on
846the correctly specified device names. A lot of the wiggle, such as running
847disklabel on a partition, has been removed.

858
859> Package Management System
860---------------------------
861
862Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
863management system. The necessary tools to build and maintain packages
864are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
865directories are in your PATH variable.
866
867In order to obtain a reasonably current snapshot of the pkgsrc tree, use
868the tarball from NetBSD:
869
870 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
871 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
872
873This tree can then be kept up to date with cvs update:
874
875 cd /usr/pkgsrc; cvs up
876
877NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
878build and install the pkgsrc bootstrap manually:
879

918You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
919FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing

941Once you have built DragonFly you have to install it over FreeBSD. Since
942DragonFly does not track changes made by FreeBSD to its include file
943hierarchy and include file pollution can cause all sorts of unexpected
944compilation issues to come up, it is best to wipe your include hierarchy
945prior to installing DragonFly. Note that you should not wipe any installed
946FreeBSD header files or binaries until after you have successfully completed
947the build steps above.

f419daca 955will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
956mess around with, such as the files in /etc/rc.d. It will also remove any
957obsolete files such as utilities and manpages that have been removed from
