15SEVERAL ISA DRIVERS REMOVED
16---------------------------
17
18The following ISA only drivers have been removed along with a couple of
19associated userland tools:
20
21aha(4)
22asc(4) & sasc(1)
23ctx
24dgb(4)
25el(4)
26gpib
27gsc(4) & sgsc(1)
28ie(4)
29labpc(4)
30le(4)
31mse(4)
32rc(4)
33rdp(4)
34spigot
35tw(4) & xten(1) & xtend(8)
36wl(4) & wlconfig(8)
37wt(4)
38
39Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
40config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
41file.
42
43If buildkernel complains about any of these drivers, just remove them
44from your kernel configuration.

55GCC 4.4 & BINUTILS 2.21
56-----------------------

b1242318
SW
58GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
59been made DragonFly's default Binutils.
30c91f0c
SW
60
61That means that any settings that set CCVER to 'gcc44' are not needed
62anymore. Instead, CCVER can be set to 'gcc41' to go back to using
63GCC 4.1.
64
b1242318
SW
65It also means that 'binutils221' as a value for BINUTILSVER has no
66effect anymore. 2.17 has been removed and 'binutils220' is available
67as an option.
68
5738210d 69The NO_GCC44 option has been removed and will not affect the build
30c91f0c
SW
70anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
71building in a similar fashion.
72

78The config file for pkg_radd has moved from /etc/settings.conf to
79/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading
80if this is needed. This warning only applies if /etc/settings.conf
81exists. pkg_radd will continue to work with defaults.

PA
90
91OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
92This shouldn't break any 3rd-party software, but you'll need to recompile your
933rd-party software if you want it to link against the new version of OpenSSL.

b79f66dd
JT
98A new loader (dloader) has been added which better handles booting from
99multiple kernel/module versions.
100
101To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
102
103 cd /usr/src
104 make buildworld
105 make installworld
106 make upgrade
107 make buildkernel KERNCONF=<KERNELNAME>
108 make installkernel KERNCONF=<KERNELNAME>
109
110Note that you must installworld and run the 'upgrade' target before
111installing the new kernel.
112
8eb0b612 113BIND
c983d16e 114-----
8eb0b612
JS
115
116BIND has been removed from the base system. The ldns and drill tools have
117been added for basic functionality. Use 'drill' where you would normally
118use nslookup or dig, or install BIND from pkgsrc. It's available as
119net/bind95, net/bind96, or net/bind97 as of this writing.
120
121This only affects older systems upgrading to 2.8. New 2.8+ installs
122include BIND as a pkgsrc package.

129Instructions on how to obtain and maintain DragonFly source code using git
130are in the development(7) manual page.
d2a0decc
MD
131
132To upgrade a DragonFly system from sources you run the following sequence:
133
134 cd /usr/src
135 make buildworld
136 make buildkernel KERNCONF=<KERNELNAME>
137 make installkernel KERNCONF=<KERNELNAME>
138 make installworld
139
140You will also want to run the 'upgrade' target to upgrade your /etc and the
141rest of your system. The upgrade target is aware of stale files created by
142older DragonFly installations and should delete them automatically.
143
144 make upgrade
145
a700883c
SW
146See the build(7) manual page for further information.
147
d2a0decc
MD
148Once you've done a full build of the world and kernel you can do incremental
149upgrades of either by using the 'quickworld' and 'quickkernel' targets
150instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 151the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 152and buildkernel as shown above, before asking for help.

156+-----------------------------------------------------------------------+
157
158In 2.1 kernel and modules has moved to boot directory. For most cases
159this is handled automatically by 'make upgrade'. A few cases needs manual
160intervention:
161
162 * When installing a kernel without first doing a make buildworld,
163 installworld and upgrade to the same DESTDIR as kernel:
164 make DESTDIR/boot directory and move kernel and modules into this boot
165 directory; also move kernel.old and modules.old.
166 Typical example is vkernel(7), use (no modules used):
167
168 cd /var/vkernel
169 mkdir boot
170 chflags noschg kernel
171 mv kernel kernel.old boot
172 chflags schg boot/kernel
173
174 * When using a boot-only partition, /boot/loader.rc needs to be edited:
175 delete occurrences of '/boot/'.
176 These occurences can normally be deleted in any case, see loader(8).

180+-----------------------------------------------------------------------+
181
182In 1.9 major changes to the disk management infrastructure have taken
183place. make upgrade may not catch all of your disk devices in /dev,
184so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
185are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
186and MAKEDEV no longer exists.
d2a0decc
MD
187
188The biggest changes in 1.9 are:
189
190(1) That whole-slice devices such as da0s1 no longer share the same device
191 id as partition c devices such as da0s1c.
192
193(2) The whole-disk device (e.g. da0) is full raw access to the disk,
194 with no snooping or reserved sectors. Consequently you cannot run
195 disklabel on this device. Instead you must run disklabel on a
196 whole-slice device.
197
198(3) The 'compatibility' partitions now use slice 0 in the device name,
199 so instead of da0a you must specify da0s0a. Also, as per (1) above,
200 accessing the disklabel for the compatibility partitions must be
201 done via slice 0 (da0s0).
202
203(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
204 and CCD now run through the disk management layer and are assigned
205 real disk management devices. VN and CCD in particular do not usually
206 use a MBR and disklabels must be accessed through the compatibility
207 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
208 don't name it 'ccd0s0' in the config file.
209
210Generally speaking, you have to get used to running fdisk and disklabel on
211the correctly specified device names. A lot of the wiggle, such as running
212disklabel on a partition, has been removed.

218> Kerberos IV
219-------------
220
221Kerberos IV (eBones) was removed from the tree, please consider moving to
222Kerberos 5 (Heimdal).
223
224> Package Management System
225---------------------------
226
227Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
228management system. The necessary tools to build and maintain packages
229are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
230directories are in your PATH variable.
231
232In order to obtain a reasonably current snapshot of the pkgsrc tree, use
233the tarball from NetBSD:
234
235 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
236 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
237
238This tree can then be kept up to date with cvs update:
239
240 cd /usr/pkgsrc; cvs up
241
242NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
243build and install the pkgsrc bootstrap manually:
244
245 cd /usr/pkgsrc/bootstrap
246 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

257The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
258The existing configuration can be converted using /etc/pam.d/convert.sh.
259Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
260the pam_skey.so module was retired, you have to remove it manually from
261your configuration, when you convert it.

984263bc 282
f419daca
MD
283You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
284FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
285FreeBSD. Note that the DragonFly buildworld target does not try to reuse
286make depend information, it starts from scratch, so no pre-cleaning of the
287object hierarchy is necessary.

306Once you have built DragonFly you have to install it over FreeBSD. Since
307DragonFly does not track changes made by FreeBSD to its include file
308hierarchy and include file pollution can cause all sorts of unexpected
309compilation issues to come up, it is best to wipe your include hierarchy
310prior to installing DragonFly. Note that you should not wipe any installed
311FreeBSD header files or binaries until after you have successfully completed
312the build steps above.

314 rm -rf /usr/include
315 mkdir /usr/include
316 make installkernel KERNCONF=<KERNELNAME>
317 make installworld
fb12f484 318
b8cbf045 319Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 320will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
321mess around with, such as the files in /etc/rc.d. It will also remove any
322obsolete files such as utilities and manpages that have been removed from
323the system since the version you're coming from. If you are unsure we
324recommend that you make a backup of at least your /etc before applying
325this step. Note that DragonFly's RC system is basically RCNG from
326FreeBSD-5, but there are some differences in the contents of the RC files.
f419daca
MD
327
328 make upgrade
329
b8cbf045
SW
330NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
331Doing so might leave your system in an unusable state.
332
f419daca 333Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
334/usr/bin, and /usr/lib, and remove any stale files that you find. Please
335report these files to the DragonFly developers so that they can be added to
336the 'upgrade' target.
