15FFS_ROOT OPTION REMOVED
16-----------------------
17
18The FFS_ROOT kernel configuration option has been finally removed, after
19having been a no-op since 4.9. That means users using a custom kernel
20configuration file that still contains it need to remove the option from
21that file.

143OPENSSL REMOVED
144---------------
145
146OpenSSL has been removed from base and replaced with a private version of
147LibreSSL. The previously installed OpenSSL libraries, headers, and man
148pages will remain on the system unless the "make upgrade" command is
149specifically instructed to remove them. To do this, define
150REMOVE_OPENSSL_FILES for the upgrade command, e.g.
151"make upgrade REMOVE_OPENSSL_FILES=yes"
152

MD
15328-Oct-2016: openssl has been replaced by ressl. It is recommended that any
154stale OpenSSL files be removed to avoid configuration scripts from using
155the stale and potentially vulnerable version, but all binaries that are
156dynamically linked to the OpenSSL libraries should be rebuilt first to
157avoid breakage.

159OPENSSH HPN REMOVED
160-------------------
161
162It has become too cumbersome to maintain HPN patches in OpenSSH in base.
163To use OpenSSH in base remove HPN config, if you have added it.
164Check files below for HPN config, see a few lines below.
165 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config
166sshd(8) will fail to start if HPN config is used.
167
168NOTE: HPN config in sshd_config will prohibit remote access to host using ssh.
169
170HPN config:
171HPNDisabled
172HPNBufferSize
173TcpRcvBuf

180OpenSSH HPN is a patch set to OpenSSH providing higher performance under some
181circumstances, especially for networking.
182If HPN functionality is needed, install security/openssh from dports.

234were 32 bits only. Those who are still using the Core 2 Duo T7500 should
235report back if there are any issues with this CPU and our regular ACPI
236P-state support.
237
238Also, compile_et(1) and com_err(3) have been removed as well. They
239should have been removed along with kerberos support, back in 2009.

276of binutils and version 2.24 becomes the alternate. There are 8 current
277CVE written against 2.24, so for security reasons version 2.25 should
278always be used.

284LOADER OPTIONS CHANGED
285----------------------
286
287Right after the development branch started, the Fred art accompanying the
288loader menu was improved. The line between Fred and the menu was removed
289by default (but can optionally be returned) and the placement shifted as
290a result. The drawing was improved, and the colored version was improved,
291changing the eyes and wing color from white to red. A new color version
292of Fred was added, one with a blue scheme.
293
294The loader menu defaults have changed since release 4.0: The vertical
295line was removed, the loader is displayed in color by default*, and the
296blue scheme is used.
297
298The loader.conf changes are:
299loader_color: option has been removed
300loader_plain: option has been added, it changed menu to monochrome
301fred_is_red: changes color scheme from blue to red
302fred_is_blue: option existed only on 4.1, it has been removed
303fred_separated: Adds line between Fred and menu (as seen previously)
304
305* If loader.conf defines "console" as "comconsole" or "console" is defined
306 in the environment as "comconsole" then color will not be displayed,
307 even if loader_plain value is "NO".

309SENDMAIL REMOVED FROM BASE
310--------------------------
311
312The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
313If the system being upgraded is still configured to use the sendmail
314binaries from base, the "make upgrade" command will fail.
315
316The administrator must change /etc/mail/mailer.conf to switch the
317mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
318command that permanently removes sendmail executables and could
319potentially break a running mail server.

346The old USB stack, along with the kernel config option "device oldusb"
347and the make.conf variable "WANT_OLDUSB" have been removed. This means
348that for custom kernel configuration files which were derived from a
349GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
350various (old USB stack specific) devices will now complain about being
351unknown:
352
353 * oldusb (obviously)
354 * natausb (not yet ported to usb4bsd)
355 * rue (not yet ported to usb4bsd)
356 * ugen (no longer needed in usb4bsd)
357 * urio (not yet ported to usb4bsd)

362GCC 5
363-----
364
365The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
366The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
367NO_CXX. The latter was never documented and the latest versions of GCC are
368partially written in C++ so a C++ compiler is no longer optional. In
369practical terms it has not been optional for many years as other base
370components are also written in C++. The resource savings by avoiding
371building Objective-C compiler is so small, the complexity added by NO_OBJC
372internally was deemed a bad tradeoff so that is the reason for its removal.
373Also note that no "info" pages are installed with GCC 5. After this entry
374was originally written, all info pages were removed from DragonFly.
375
376GCC 5.1 has been designated as the primary compiler. As such, there is a
377new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
378the designated secondary compiler, GCC 4.7. However, while DPorts
379primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
380if building ports from source is desired, don't block building of the
381secondary compiler.

515GCC 4.7
516-------
517
518DragonFly has switched base compilers. GCC 4.7 is now the default
519compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
520variable ceases to work now.
521
522Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
523/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
524highly discouraged. There are a few packages in pkgsrc that do not build
525with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
526this time, it is recommended to keep both compilers on the base system.

777+-----------------------------------------------------------------------+
778
779In 2.1 kernel and modules has moved to boot directory. For most cases
780this is handled automatically by 'make upgrade'. A few cases needs manual
781intervention:
782
783 * When installing a kernel without first doing a make buildworld,
784 installworld and upgrade to the same DESTDIR as kernel:
785 make DESTDIR/boot directory and move kernel and modules into this boot
786 directory; also move kernel.old and modules.old.
787 Typical example is vkernel(7), use (no modules used):
788
789 cd /var/vkernel
790 mkdir boot
791 chflags noschg kernel
792 mv kernel kernel.old boot
793 chflags schg boot/kernel
794
795 * When using a boot-only partition, /boot/loader.rc needs to be edited:
796 delete occurrences of '/boot/'.
797 These occurences can normally be deleted in any case, see loader(8).

802
803In 1.9 major changes to the disk management infrastructure have taken
804place. make upgrade may not catch all of your disk devices in /dev,
805so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
806are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
807and MAKEDEV no longer exists.
d2a0decc
MD
808
809The biggest changes in 1.9 are:
810
811(1) That whole-slice devices such as da0s1 no longer share the same device
812 id as partition c devices such as da0s1c.
813
814(2) The whole-disk device (e.g. da0) is full raw access to the disk,
815 with no snooping or reserved sectors. Consequently you cannot run
816 disklabel on this device. Instead you must run disklabel on a
817 whole-slice device.
818
819(3) The 'compatibility' partitions now use slice 0 in the device name,
820 so instead of da0a you must specify da0s0a. Also, as per (1) above,
821 accessing the disklabel for the compatibility partitions must be
822 done via slice 0 (da0s0).
823
824(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
825 and CCD now run through the disk management layer and are assigned
826 real disk management devices. VN and CCD in particular do not usually
827 use a MBR and disklabels must be accessed through the compatibility
828 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
829 don't name it 'ccd0s0' in the config file.
830
831Generally speaking, you have to get used to running fdisk and disklabel on
832the correctly specified device names. A lot of the wiggle, such as running
833disklabel on a partition, has been removed.

845> Package Management System
846---------------------------
847
848Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
849management system. The necessary tools to build and maintain packages
850are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
851directories are in your PATH variable.
852
853In order to obtain a reasonably current snapshot of the pkgsrc tree, use
854the tarball from NetBSD:
855
856 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
857 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
858
859This tree can then be kept up to date with cvs update:
860
861 cd /usr/pkgsrc; cvs up
862
863NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
864build and install the pkgsrc bootstrap manually:

927Once you have built DragonFly you have to install it over FreeBSD. Since
928DragonFly does not track changes made by FreeBSD to its include file
929hierarchy and include file pollution can cause all sorts of unexpected
930compilation issues to come up, it is best to wipe your include hierarchy
931prior to installing DragonFly. Note that you should not wipe any installed
932FreeBSD header files or binaries until after you have successfully completed
933the build steps above.

b8cbf045
SW
942mess around with, such as the files in /etc/rc.d. It will also remove any
943obsolete files such as utilities and manpages that have been removed from
944the system since the version you're coming from. If you are unsure we
945recommend that you make a backup of at least your /etc before applying
946this step. Note that DragonFly's RC system is basically RCNG from
947FreeBSD-5, but there are some differences in the contents of the RC files.
