Note: Upgrades are only supported from one release to the release immediately following it. Do not skip releases.
Upgrading is a convenient way to bring your OpenBSD system up to the most recent version. However, the results are not intended to precisely match the results of a wipe-and-reload installation. Old library files in particular are not removed in the upgrade process, as they may be required by older applications that may or may not be upgraded at this time. If you REALLY wish to get rid of all these old files, you would probably be better off reinstalling from scratch.
To quickly remove all packages from your system:
After the upgrade, install the new versions of these applications.pkg_delete -q /var/db/pkg/*
Note that, with OpenBSD 3.7, the pkg tools now support in-place updating
pkg_add -r. This has been checked to work with most
packages, in particular with the CD packages available in 3.5 or 3.6.
Some important points apply:
pkg_add -rdoes not do global updates, but needs to be told which packages to update. Noting down the installed packages name with pkg_info, matching each package name to its newer equivalent, and running one
pkg_add -r -q list_of_new_pkgsshould work in most cases.
i386 and macppc users:
Due to the switch to gcc3, you must remove the
directory before upgrading, regardless whether you plan to use the install
media or not:
rm -rf /usr/include/g++
Sometimes, one needs to do an upgrade of a machine when one can't easily use the normal upgrade process. One can usually do this by carefully following a process similar to a source-based upgrade:
Note the extra steps for copying over the primary kernel: those are done to ensure that there is always a valid copy of the kernel on the disk that the system can boot from should there be a really badly timed power outage or system crash.cd /path rm /obsd ; ln /bsd /obsd && cp bsd /nbsd && mv /nbsd /bsd cp bsd.rd bsd.mp /
/etc/firmwarefiles: Due to the fact that some uploaded "firmware" blobs were relocated from the kernel to files in the
/etc/firmwaredirectory, there are a few drivers which will break if there is no uploadable firmware file available when the new kernel boots. This will impact users of only a few devices, though all users can use this step without harm. To extract the firmware files from
base37.tgz, use the following as root:
before the next step.cd / tar xzpf /path/base37.tgz "*etc/firmware/*"
reboot!), but often a new userland will NOT work on the old kernel.
Note: not all file sets will need to be installed for all applications, however, if you installed a file set originally, you should certainly upgrade it with the new file set now. Also note that the files incd / tar xzpf /path/base37.tgz tar xzpf /path/comp37.tgz tar xzpf /path/game37.tgz tar xzpf /path/man37.tgz tar xzpf /path/misc37.tgz tar xzpf /path/xbase37.tgz tar xzpf /path/xfont37.tgz tar xzpf /path/xserv37.tgz tar xzpf /path/xshare37.tgz
/etcare handled separately below, so
xetc37.tgzare NOT unpacked here.
/dev. The new MAKEDEV file will be copied to /dev by the installation of
base37.tgz, so you simply need to do the following:
cd /dev ./MAKEDEV all
Nov 1 12:47:05 puffy sm-mta: filesys_update failed: No such file or directory, fs=., avail=-1, blocksize=380204These messages can be safely ignored, or you may wish to halt sendmail(8) during the upgrade process.
These steps will add both the new users and their corresponding groups. Your environment may allow you to copy/paste those commands.useradd -u84 -g=uid -c"FTP Daemon" -d/var/empty -s/sbin/nologin _ftp useradd -u85 -g=uid -c"OSPF Daemon" -d/var/empty -s/sbin/nologin _ospfd
X.org replaces XFree86:
Due the XFree86 project's change of license, OpenBSD has switched to the
X.org project's X Window System.
The X11 configuration files must be updated, however.
Many users can simply unpack
xetc37.tgz without concern:
If you have made important manual changes to the files incd / tar xzpf /path/xetc37.tgz
/etc/X11for any reason, you should NOT unpack the
xetc37.tgzfile as above, but rather manually merge your changes into the new files.
If you have an
/etc/X11/XF86Config file that works on OpenBSD
3.6, renaming it to
/etc/X11/xorg.conf will probably give you a
fully functioning X Window system on OpenBSD 3.7.
You may also find that the newer versions of X are much more
"self-configuring" than earlier versions, and you may not need an
/etc/X11/xorg.conf file at all now, depending on your hardware.
bgpd(8) behavior change: The new rde route-age [evaluate|ignore] changed behavior of bgpd. Until now evaluate was the implicit default but now the default is ignore. Route age evaluation is not specified in RFC 1771 and results in non deterministic decisions in preference for more stable links.
pfsync takes syncdev instead of syncif: When configuring the pfsync device, use 'syncdev' instead of the deprecated keyword 'syncif'.
OpenNTPD now sets the time immediately at startup: As of OpenBSD 3.7, OpenNTPD is able to make large time corrections, so it is no longer necessary to run rdate(8) to set the time before starting ntpd(8). You may wish to disable rdate(8) in your rc.conf.local (or rc.conf) file if you had opted to do this.
etc37.tgzfiles to a temporary location:
Files that can probably be copied fromcd /tmp tar xzpf /path/etc37.tgz
Note that it IS possible to locally modify these files, if this has been done, manual merging will be needed. Here are copy/paste lines for copying these files, assuming you unpackedchangelist daily fbtab moduli netstart ospfd.conf rc security services mtree/*
etc37.tgzin the above recommended place:
cd /tmp/etc cp changelist daily fbtab moduli netstart ospfd.conf rc security services /etc cp mtree/* /etc/mtree/
Files that must be manually merged, respecting any local changes made to them, if they were modified from the default, otherwise, just copy them over, too:
Finally, use mtree(8) to create any new directories:ftpusers rc.conf spamd.conf sysctl.conf mail/aliases skel/.cshrc skel/.profile
mtree -qdef /etc/mtree/4.4BSD.dist -p / -u
