15EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO
16-------------------------------------------------
17
18The est(4) driver has been removed. All CPUs it supported (except one)
19were 32 bits only. Those who are still using the Core 2 Duo T7500 should
20report back if there are any issues with this CPU and our regular ACPI
21P-state support.
22
23Also, compile_et(1) and com_err(3) have been removed as well. They
24should have been removed along with kerberos support, back in 2009.

56BINUTILS 2.25 REPLACES 2.22, PRIMARY
57------------------------------------
58
59The oldest of the two versions of Binutils, version 2.22, was removed
60and replaced with Binutils 2.25. It becomes the primary version version
61of binutils and version 2.24 becomes the alternate. There are 8 current
62CVE written against 2.24, so for security reasons version 2.25 should
63always be used.
64
65The accepted values of BINUTILSVER are now "binutils225" (default) and
66"binutils224". The building of Binutils 2.24 can be prevented by setting
67NO_ALTBINUTILS=yes in make.conf.

69LOADER OPTIONS CHANGED
70----------------------
71
72Right after the development branch started, the Fred art accompanying the
73loader menu was improved. The line between Fred and the menu was removed
74by default (but can optionally be returned) and the placement shifted as
75a result. The drawing was improved, and the colored version was improved,
76changing the eyes and wing color from white to red. A new color version
77of Fred was added, one with a blue scheme.
78
79The loader menu defaults have changed since release 4.0: The vertical
80line was removed, the loader is displayed in color by default*, and the
81blue scheme is used.
82
83The loader.conf changes are:
84loader_color: option has been removed
85loader_plain: option has been added, it changed menu to monochrome
86fred_is_red: changes color scheme from blue to red
87fred_is_blue: option existed only on 4.1, it has been removed
88fred_separated: Adds line between Fred and menu (as seen previously)
89
90* If loader.conf defines "console" as "comconsole" or "console" is defined
91 in the environment as "comconsole" then color will not be displayed,
92 even if loader_plain value is "NO".

94SENDMAIL REMOVED FROM BASE
95--------------------------
96
97The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
98If the system being upgraded is still configured to use the sendmail
99binaries from base, the "make upgrade" command will fail.
100
101The administrator must change /etc/mail/mailer.conf to switch the
102mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
103command that permanently removes sendmail executables and could
104potentially break a running mail server.
105
106Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
107detailed instructions on how to configure the MTA selection.

128OLD USB DRIVERS REMOVED
129-----------------------
130
131The old USB stack, along with the kernel config option "device oldusb"
132and the make.conf variable "WANT_OLDUSB" have been removed. This means
133that for custom kernel configuration files which were derived from a
134GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
135various (old USB stack specific) devices will now complain about being
136unknown:
137
138 * oldusb (obviously)
139 * natausb (not yet ported to usb4bsd)
140 * rue (not yet ported to usb4bsd)
141 * ugen (no longer needed in usb4bsd)
142 * urio (not yet ported to usb4bsd)
143 * uscanner (no longer needed in usb4bsd)
144
145They should be removed or commented out in such custom kernel configs.

147GCC 5
148-----
149
150The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
151The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
152NO_CXX. The latter was never documented and the latest versions of GCC are
153partially written in C++ so a C++ compiler is no longer optional. In
154practical terms it has not been optional for many years as other base
155components are also written in C++. The resource savings by avoiding
156building Objective-C compiler is so small, the complexity added by NO_OBJC
157internally was deemed a bad tradeoff so that is the reason for its removal.
158Also note that no "info" pages are installed with GCC 5. After this entry
159was originally written, all info pages were removed from DragonFly.
160
161GCC 5.1 has been designated as the primary compiler. As such, there is a
162new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
163the designated secondary compiler, GCC 4.7. However, while DPorts
164primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
165if building ports from source is desired, don't block building of the
166secondary compiler.

174
175DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
176the default now (even on single-core systems), both for, like, 21 months.
177We kept the options around as no-ops as a convenience, to allow people
178using the same config for the then current release and the then current
179master. That period is now over, so any configs still having those
180options have to be adjusted.

188DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
189--------------------------------------------------------------------

191The default driver for those controllers is now mrsas(4) due to reports
192of file system corruption using the mfi(4) driver. The whole issue (and
193how to deal with potential problems when switching) was explained here:
194
195http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html

203The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
204and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
205removed in kernel configs derived from X86_64_GENERIC.

300GCC 4.7
301-------
302
303DragonFly has switched base compilers. GCC 4.7 is now the default
304compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
305variable ceases to work now.
306
307Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
308/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
309highly discouraged. There are a few packages in pkgsrc that do not build
310with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
311this time, it is recommended to keep both compilers on the base system.

513 make buildkernel KERNCONF=<KERNELNAME>

522BIND has been removed from the base system. The ldns and drill tools have
523been added for basic functionality. Use 'drill' where you would normally
524use nslookup or dig, or install BIND from pkgsrc. It's available as
525net/bind95, net/bind96, or net/bind97 as of this writing.
526
527This only affects older systems upgrading to 2.8. New 2.8+ installs
528include BIND as a pkgsrc package.

538To upgrade a DragonFly system from sources you run the following sequence:
539
540 cd /usr/src
541 make buildworld
542 make buildkernel KERNCONF=<KERNELNAME>
543 make installkernel KERNCONF=<KERNELNAME>
544 make installworld
545
546You will also want to run the 'upgrade' target to upgrade your /etc and the
547rest of your system. The upgrade target is aware of stale files created by
548older DragonFly installations and should delete them automatically.
549
550 make upgrade

554Once you've done a full build of the world and kernel you can do incremental
555upgrades of either by using the 'quickworld' and 'quickkernel' targets
556instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 557the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 558and buildkernel as shown above, before asking for help.

563
564In 2.1 kernel and modules has moved to boot directory. For most cases
565this is handled automatically by 'make upgrade'. A few cases needs manual
566intervention:
567
568 * When installing a kernel without first doing a make buildworld,
569 installworld and upgrade to the same DESTDIR as kernel:
570 make DESTDIR/boot directory and move kernel and modules into this boot
571 directory; also move kernel.old and modules.old.
572 Typical example is vkernel(7), use (no modules used):
573
574 cd /var/vkernel
575 mkdir boot
576 chflags noschg kernel
577 mv kernel kernel.old boot
578 chflags schg boot/kernel
579
580 * When using a boot-only partition, /boot/loader.rc needs to be edited:
581 delete occurrences of '/boot/'.
582 These occurences can normally be deleted in any case, see loader(8).

587
588In 1.9 major changes to the disk management infrastructure have taken
589place. make upgrade may not catch all of your disk devices in /dev,
590so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
591are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
592and MAKEDEV no longer exists.
d2a0decc
MD
593
594The biggest changes in 1.9 are:
595
596(1) That whole-slice devices such as da0s1 no longer share the same device
597 id as partition c devices such as da0s1c.
598
599(2) The whole-disk device (e.g. da0) is full raw access to the disk,
600 with no snooping or reserved sectors. Consequently you cannot run
601 disklabel on this device. Instead you must run disklabel on a
602 whole-slice device.
603
604(3) The 'compatibility' partitions now use slice 0 in the device name,
605 so instead of da0a you must specify da0s0a. Also, as per (1) above,
606 accessing the disklabel for the compatibility partitions must be
607 done via slice 0 (da0s0).
608
609(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
610 and CCD now run through the disk management layer and are assigned
611 real disk management devices. VN and CCD in particular do not usually
612 use a MBR and disklabels must be accessed through the compatibility
613 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
614 don't name it 'ccd0s0' in the config file.
615
616Generally speaking, you have to get used to running fdisk and disklabel on
617the correctly specified device names. A lot of the wiggle, such as running
618disklabel on a partition, has been removed.

627Kerberos IV (eBones) was removed from the tree, please consider moving to
628Kerberos 5 (Heimdal).
629
630> Package Management System
631---------------------------
632
633Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
634management system. The necessary tools to build and maintain packages
635are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
636directories are in your PATH variable.
637
638In order to obtain a reasonably current snapshot of the pkgsrc tree, use
639the tarball from NetBSD:
640
641 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
642 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
643
644This tree can then be kept up to date with cvs update:
645
646 cd /usr/pkgsrc; cvs up
647
648NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
649build and install the pkgsrc bootstrap manually:
650
651 cd /usr/pkgsrc/bootstrap
652 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

689You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
690FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
691FreeBSD. Note that the DragonFly buildworld target does not try to reuse
692make depend information, it starts from scratch, so no pre-cleaning of the
693object hierarchy is necessary.

712Once you have built DragonFly you have to install it over FreeBSD. Since
713DragonFly does not track changes made by FreeBSD to its include file
714hierarchy and include file pollution can cause all sorts of unexpected
715compilation issues to come up, it is best to wipe your include hierarchy
716prior to installing DragonFly. Note that you should not wipe any installed
717FreeBSD header files or binaries until after you have successfully completed
718the build steps above.

722 make installkernel KERNCONF=<KERNELNAME>
723 make installworld
fb12f484 724
b8cbf045 725Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 726will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
727mess around with, such as the files in /etc/rc.d. It will also remove any
728obsolete files such as utilities and manpages that have been removed from
729the system since the version you're coming from. If you are unsure we
730recommend that you make a backup of at least your /etc before applying
731this step. Note that DragonFly's RC system is basically RCNG from
732FreeBSD-5, but there are some differences in the contents of the RC files.

733
734 make upgrade
735
b8cbf045
SW
736NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
737Doing so might leave your system in an unusable state.
738
f419daca 739Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
740/usr/bin, and /usr/lib, and remove any stale files that you find. Please
741report these files to the DragonFly developers so that they can be added to
742the 'upgrade' target.
