Upgrading the OpenBSD System and Kernel

By Kurt Seifried [email protected],

It doesn't really get much better then: http://www.openbsd.org/faq/upgrade-minifaq.html. I am not going to rehash this page, however I have a quick summary of things Iuse, and some extra tips and tricks.

I use the following commands to keep my machines at OpenBSD-current, they can easily be modified (one line change) to keep a system at 3.2-stable or whatever you want.

Updating the local source tree

The following commands will retrieve the “current” OpenBSD source tree (I like to live on the edge):

export [email protected]:/cvs
export CVS_RSH=/usr/bin/ssh
cd /usr
cvs -q get -P src

Updating the kernel

Updating the kernel is a pretty straightforward process, make sure you clean up after the last compile, config a kernel, then compile and install it:

rm -rf /usr/obj
mkdir /usr/obj
cd /usr/src
make obj

cd /usr/src/sys/arch/i386/conf
config GENERIC
cd ../compile/GENERIC

make clean
make depend
make
cp /bsd /bsd.old 
cp bsd /bsd

After this script runs you will want to reboot the system.

Updating the system (userland)

Updating all of OpenBSD userland (i.e. All programs, libraries, etc, that ship with OpenBSD) is quite simple:

cd /usr/src
make build

After this runs you will probably want to reboot the system if nothing else to ensure the system will reboot properly (better to find out now rather then later).

CVS tags

CVS relies on tags, a CVS repository often hosts different branches and versions of the same project, OpenBSD is no exception. The major OpenBSD CVS servers typically have OpenBSD-current, -stable, -release, as well as previous versions. To keep a system at a “stable” version as opposed to current simply modify the following line:

cvs -q get -P src

To the following:

cvs -q get -rOPENBSD_3_1 -P src

This would retrieve 3.1.
