13+         UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD			+
14+-----------------------------------------------------------------------+
15
16OpenSSL
17========
18
19OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
20This shouldn't break any 3rd-party software, but you'll need to recompile your
213rd-party software if you want it to link against the new version of OpenSSL.
22
23Loader
24=======
25
26A new loader (dloader) has been added which better handles booting from
27multiple kernel/module versions.
28
29To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
30
31	cd /usr/src
32	make buildworld
33	make installworld
34	make upgrade
35	make buildkernel KERNCONF=<KERNELNAME>
36	make installkernel KERNCONF=<KERNELNAME>
37
38Note that you must installworld and run the 'upgrade' target before
39installing the new kernel.
40
41BIND
42=====
43
44BIND has been removed from the base system.  The ldns and drill tools have
45been added for basic functionality.  Use 'drill' where you would normally
46use nslookup or dig, or install BIND from pkgsrc.  It's available as
47net/bind95, net/bind96, or net/bind97 as of this writing.
48
49This only affects older systems upgrading to 2.8.  New 2.8+ installs
50include BIND as a pkgsrc package.

53+         UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM		+
54+				GENERAL					+
55+-----------------------------------------------------------------------+
56
57Instructions on how to obtain and maintain DragonFly source code using git
58are in the development(7) manual page.
59
60To upgrade a DragonFly system from sources you run the following sequence:
61
62	cd /usr/src
63	make buildworld
64	make buildkernel KERNCONF=<KERNELNAME>
65	make installkernel KERNCONF=<KERNELNAME>
66	make installworld
67
68You will also want to run the 'upgrade' target to upgrade your /etc and the
69rest of your system.  The upgrade target is aware of stale files created by
70older DragonFly installations and should delete them automatically.
71
72	make upgrade
73
74See the build(7) manual page for further information.
75
76Once you've done a full build of the world and kernel you can do incremental
77upgrades of either by using the 'quickworld' and 'quickkernel' targets
78instead of 'buildworld' and 'buildkernel'.  If you have any problems with
79the quick targets, try updating your repo first, and then a full buildworld
80and buildkernel as shown above, before asking for help.
81
82+-----------------------------------------------------------------------+
83+         UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1		+
84+-----------------------------------------------------------------------+
85
86In 2.1 kernel and modules has moved to boot directory.  For most cases
87this is handled automatically by 'make upgrade'.  A few cases needs manual
88intervention:
89
90 * When installing a kernel without first doing a make buildworld,
91   installworld and upgrade to the same DESTDIR as kernel:
92   make DESTDIR/boot directory and move kernel and modules into this boot
93   directory; also move kernel.old and modules.old.
94   Typical example is vkernel(7), use (no modules used):
95
96	cd /var/vkernel
97	mkdir boot
98	chflags noschg kernel
99	mv kernel kernel.old boot
100	chflags schg boot/kernel
101
102 * When using a boot-only partition, /boot/loader.rc needs to be edited:
103   delete occurrences of '/boot/'.
104   These occurences can normally be deleted in any case, see loader(8).
105
106+-----------------------------------------------------------------------+
107+         UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9		+
108+-----------------------------------------------------------------------+
109
110In 1.9 major changes to the disk management infrastructure have taken
111place.  make upgrade may not catch all of your disk devices in /dev,
112so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
113are all of your disk devices.  HOWEVER, from late 2.3 on we run devfs
114and MAKEDEV no longer exists.
115
116The biggest changes in 1.9 are:
117
118(1) That whole-slice devices such as da0s1 no longer share the same device
119    id as partition c devices such as da0s1c.
120
121(2) The whole-disk device (e.g. da0) is full raw access to the disk,
122    with no snooping or reserved sectors.  Consequently you cannot run
123    disklabel on this device.  Instead you must run disklabel on a
124    whole-slice device.
125
126(3) The 'compatibility' partitions now use slice 0 in the device name,
127    so instead of da0a you must specify da0s0a.  Also, as per (1) above,
128    accessing the disklabel for the compatibility partitions must be
129    done via slice 0 (da0s0).
130
131(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
132    and CCD now run through the disk management layer and are assigned
133    real disk management devices.   VN and CCD in particular do not usually
134    use a MBR and disklabels must be accessed through the compatibility
135    slice 0.  Your /etc/ccd.conf file still specifies 'ccd0', though, you
136    don't name it 'ccd0s0' in the config file.
137
138Generally speaking, you have to get used to running fdisk and disklabel on
139the correctly specified device names.  A lot of the wiggle, such as running
140disklabel on a partition, has been removed.

145
146> Kerberos IV
147-------------
148
149Kerberos IV (eBones) was removed from the tree, please consider moving to
150Kerberos 5 (Heimdal).
151
152> Package Management System
153---------------------------
154
155Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
156management system.  The necessary tools to build and maintain packages
157are provided in /usr/pkg/bin and /usr/pkg/sbin.  Make sure that these
158directories are in your PATH variable.
159
160In order to obtain a reasonably current snapshot of the pkgsrc tree, use
161the tarball from NetBSD:
162
163	fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
164	cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
165
166This tree can then be kept up to date with cvs update:
167
168	cd /usr/pkgsrc; cvs up
169
170NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
171build and install the pkgsrc bootstrap manually:
172
173	cd /usr/pkgsrc/bootstrap
174	./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

179+         DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD)                       +
180+-----------------------------------------------------------------------+
181
182The compatibility shims for the build environment have been removed, you
183have to update to DragonFly 1.2 release branch first.
184
185The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
186The existing configuration can be converted using /etc/pam.d/convert.sh.
187Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
188the pam_skey.so module was retired, you have to remove it manually from
189your configuration, when you convert it.
190
191> Required user and group IDs when upgrading from either FreeBSD or DragonFly
192---------------------
193
194The following users may be missing from your password file.  Use vipw and
195add any that are missing:
196
197smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin
198_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin
199
200The following groups may be missing from your group file.  Use vi /etc/group
201and add any that are missing:
202
203smmsp:*:25:
204authpf:*:63:
205_pflogd:*:64:
206
207
208> Upgrading to DragonFly from FreeBSD
209---------------------
210
211You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
212FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
213FreeBSD.  Note that the DragonFly buildworld target does not try to reuse
214make depend information, it starts from scratch, so no pre-cleaning of the
215object hierarchy is necessary.
216
217	# get the CVS repository (it is placed in /home/dcvs, 500MB).
218	# Please use the -h option and a mirror site to pull the
219	# initial repository, but feel free to use the main repository
220	# machine to pull updates.
221	cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
222	# install the source from the CVS hierarchy (remove preexisting
223	# FreeBSD src first) (500MB)
224	cd /usr
225	rm -rf src
226	cvs -R -d /home/dcvs checkout -P src
227
228	# build it (500MB used in /usr/obj)
229	#
230	cd /usr/src
231	make buildworld
232	make buildkernel KERNCONF=<KERNELNAME>
233
234Once you have built DragonFly you have to install it over FreeBSD.  Since
235DragonFly does not track changes made by FreeBSD to its include file
236hierarchy and include file pollution can cause all sorts of unexpected
237compilation issues to come up, it is best to wipe your include hierarchy
238prior to installing DragonFly.  Note that you should not wipe any installed
239FreeBSD header files or binaries until after you have successfully completed
240the build steps above.
241
242	rm -rf /usr/include
243	mkdir /usr/include
244	make installkernel KERNCONF=<KERNELNAME>
245	make installworld
246
247Then you need to upgrade your system.  DragonFly's 'make upgrade' target
248will unconditionally upgrade the /etc files that sysops do not usually
249mess around with, such as the files in /etc/rc.d.  It will also remove any
250obsolete files such as utilities and manpages that have been removed from
251the system since the version you're coming from.  If you are unsure we
252recommend that you make a backup of at least your /etc before applying
253this step.  Note that DragonFly's RC system is basically RCNG from
254FreeBSD-5, but there are some differences in the contents of the RC files.
255
256	make upgrade
257
258NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
259Doing so might leave your system in an unusable state.
260
261Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
262/usr/bin, and /usr/lib, and remove any stale files that you find.  Please
263report these files to the DragonFly developers so that they can be added to
264the 'upgrade' target.
