15BINUTILS 2.25 REPLACES 2.22, PRIMARY
16------------------------------------
17
18The oldest of the two versions of Binutils, version 2.22, was removed
19and replaced with Binutils 2.25. It becomes the primary version version
20of binutils and version 2.24 becomes the alternate. There are 8 current
21CVE written against 2.24, so for security reasons version 2.25 should
22always be used.
23
24The accepted values of BINUTILSVER are now "binutils225" (default) and
25"binutils224". The building of Binutils 2.24 can be prevented by setting
26NO_ALTBINUTILS=yes in make.conf.

28LOADER OPTIONS CHANGED
29----------------------
30
31Right after the development branch started, the Fred art accompanying the
32loader menu was improved. The line between Fred and the menu was removed
33by default (but can optionally be returned) and the placement shifted as
34a result. The drawing was improved, and the colored version was improved,
35changing the eyes and wing color from white to red. A new color version
36of Fred was added, one with a blue scheme.
37
38The loader menu defaults have changed since release 4.0: The vertical
39line was removed, the loader is displayed in color by default*, and the
40blue scheme is used.
41
42The loader.conf changes are:
43loader_color: option has been removed
44loader_plain: option has been added, it changed menu to monochrome
45fred_is_red: changes color scheme from blue to red
46fred_is_blue: option existed only on 4.1, it has been removed
47fred_separated: Adds line between Fred and menu (as seen previously)
48
49* If loader.conf defines "console" as "comconsole" or "console" is defined
50 in the environment as "comconsole" then color will not be displayed,
51 even if loader_plain value is "NO".

53SENDMAIL REMOVED FROM BASE
54--------------------------
55
56The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma).
57If the system being upgraded is still configured to use the sendmail
58binaries from base, the "make upgrade" command will fail.
59
60The administrator must change /etc/mail/mailer.conf to switch the
61mailwrapper to dma or a DPorts-based MTA prior to running the upgrade
62command that permanently removes sendmail executables and could
63potentially break a running mail server.
64
65Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for
66detailed instructions on how to configure the MTA selection.

80hw.snd.default_unit to a different number will change it.

87OLD USB DRIVERS REMOVED
88-----------------------
89
90The old USB stack, along with the kernel config option "device oldusb"
91and the make.conf variable "WANT_OLDUSB" have been removed. This means
92that for custom kernel configuration files which were derived from a
93GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
94various (old USB stack specific) devices will now complain about being
95unknown:
96
97 * oldusb (obviously)
98 * natausb (not yet ported to usb4bsd)
99 * rue (not yet ported to usb4bsd)
100 * ugen (no longer needed in usb4bsd)
101 * urio (not yet ported to usb4bsd)
102 * uscanner (no longer needed in usb4bsd)
103
104They should be removed or commented out in such custom kernel configs.

106GCC 5
107-----
108
109The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1.
110The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and
111NO_CXX. The latter was never documented and the latest versions of GCC are
112partially written in C++ so a C++ compiler is no longer optional. In
113practical terms it has not been optional for many years as other base
114components are also written in C++. The resource savings by avoiding
115building Objective-C compiler is so small, the complexity added by NO_OBJC
116internally was deemed a bad tradeoff so that is the reason for its removal.
117Also note that no "info" pages are installed with GCC 5. After this entry
118was originally written, all info pages were removed from DragonFly.
119
120GCC 5.1 has been designated as the primary compiler. As such, there is a
121new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of
122the designated secondary compiler, GCC 4.7. However, while DPorts
123primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so
124if building ports from source is desired, don't block building of the
125secondary compiler.

39b3e0a1
SW
132-------------------------------------------
133
134DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
135the default now (even on single-core systems), both for, like, 21 months.
136We kept the options around as no-ops as a convenience, to allow people
137using the same config for the then current release and the then current
138master. That period is now over, so any configs still having those
139options have to be adjusted.

147DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
148--------------------------------------------------------------------
149
150The default driver for those controllers is now mrsas(4) due to reports
151of file system corruption using the mfi(4) driver. The whole issue (and
152how to deal with potential problems when switching) was explained here:
153
154http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html
155
156A tunable is provided for letting those controllers still attach via
157the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page).

159OLDER NETWORK DRIVERS MOVED TO I386 ONLY
160----------------------------------------

162The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
163and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
164removed in kernel configs derived from X86_64_GENERIC.

259GCC 4.7
260-------
261
262DragonFly has switched base compilers. GCC 4.7 is now the default
263compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
264variable ceases to work now.
265
266Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
267/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
268highly discouraged. There are a few packages in pkgsrc that do not build
269with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
270this time, it is recommended to keep both compilers on the base system.

272SMP OPTION REMOVED
273------------------
274

277remove it.

345and uaudio.
346
347It is not yet the default. To activate it, WANT_USB4BSD=yes has to
c7200221
SW
348be put in make.conf and device "usb4bsd" (quotes needed) has to
349replace device usb in the kernel config. After that, a full

484net/bind95, net/bind96, or net/bind97 as of this writing.
485
486This only affects older systems upgrading to 2.8. New 2.8+ installs
487include BIND as a pkgsrc package.

497To upgrade a DragonFly system from sources you run the following sequence:
498
499 cd /usr/src
500 make buildworld
501 make buildkernel KERNCONF=<KERNELNAME>
502 make installkernel KERNCONF=<KERNELNAME>
503 make installworld
504
505You will also want to run the 'upgrade' target to upgrade your /etc and the
506rest of your system. The upgrade target is aware of stale files created by
507older DragonFly installations and should delete them automatically.
508
509 make upgrade

511See the build(7) manual page for further information.

513Once you've done a full build of the world and kernel you can do incremental
514upgrades of either by using the 'quickworld' and 'quickkernel' targets
515instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 516the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 517and buildkernel as shown above, before asking for help.

522
523In 2.1 kernel and modules has moved to boot directory. For most cases
524this is handled automatically by 'make upgrade'. A few cases needs manual
525intervention:
526
527 * When installing a kernel without first doing a make buildworld,
528 installworld and upgrade to the same DESTDIR as kernel:
529 make DESTDIR/boot directory and move kernel and modules into this boot
530 directory; also move kernel.old and modules.old.
531 Typical example is vkernel(7), use (no modules used):
532
533 cd /var/vkernel
534 mkdir boot
535 chflags noschg kernel
536 mv kernel kernel.old boot
537 chflags schg boot/kernel
538
539 * When using a boot-only partition, /boot/loader.rc needs to be edited:
540 delete occurrences of '/boot/'.
541 These occurences can normally be deleted in any case, see loader(8).

546
547In 1.9 major changes to the disk management infrastructure have taken
548place. make upgrade may not catch all of your disk devices in /dev,
549so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
550are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
551and MAKEDEV no longer exists.
d2a0decc
MD
552
553The biggest changes in 1.9 are:
554
555(1) That whole-slice devices such as da0s1 no longer share the same device
556 id as partition c devices such as da0s1c.
557
558(2) The whole-disk device (e.g. da0) is full raw access to the disk,
559 with no snooping or reserved sectors. Consequently you cannot run
560 disklabel on this device. Instead you must run disklabel on a
561 whole-slice device.
562
563(3) The 'compatibility' partitions now use slice 0 in the device name,
564 so instead of da0a you must specify da0s0a. Also, as per (1) above,
565 accessing the disklabel for the compatibility partitions must be
566 done via slice 0 (da0s0).
567
568(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
569 and CCD now run through the disk management layer and are assigned
570 real disk management devices. VN and CCD in particular do not usually
571 use a MBR and disklabels must be accessed through the compatibility
572 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
573 don't name it 'ccd0s0' in the config file.
574
575Generally speaking, you have to get used to running fdisk and disklabel on
576the correctly specified device names. A lot of the wiggle, such as running
577disklabel on a partition, has been removed.

586Kerberos IV (eBones) was removed from the tree, please consider moving to
587Kerberos 5 (Heimdal).
588
589> Package Management System
590---------------------------
591
592Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
593management system. The necessary tools to build and maintain packages
594are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
595directories are in your PATH variable.
596
597In order to obtain a reasonably current snapshot of the pkgsrc tree, use
598the tarball from NetBSD:
599
600 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
601 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
602
603This tree can then be kept up to date with cvs update:
604
605 cd /usr/pkgsrc; cvs up
606
607NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
608build and install the pkgsrc bootstrap manually:
609
610 cd /usr/pkgsrc/bootstrap
611 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

648You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
649FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
650FreeBSD. Note that the DragonFly buildworld target does not try to reuse
651make depend information, it starts from scratch, so no pre-cleaning of the
652object hierarchy is necessary.

671Once you have built DragonFly you have to install it over FreeBSD. Since
672DragonFly does not track changes made by FreeBSD to its include file
673hierarchy and include file pollution can cause all sorts of unexpected
674compilation issues to come up, it is best to wipe your include hierarchy
675prior to installing DragonFly. Note that you should not wipe any installed
676FreeBSD header files or binaries until after you have successfully completed
677the build steps above.

fb12f484 683
b8cbf045 684Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 685will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
686mess around with, such as the files in /etc/rc.d. It will also remove any
687obsolete files such as utilities and manpages that have been removed from
688the system since the version you're coming from. If you are unsure we
689recommend that you make a backup of at least your /etc before applying
690this step. Note that DragonFly's RC system is basically RCNG from
691FreeBSD-5, but there are some differences in the contents of the RC files.
f419daca
MD
692
693 make upgrade
694
b8cbf045
SW
695NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
696Doing so might leave your system in an unusable state.
697
f419daca 698Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
699/usr/bin, and /usr/lib, and remove any stale files that you find. Please
700report these files to the DragonFly developers so that they can be added to
701the 'upgrade' target.
