OpenBSD Upgrade Guide: 3.4 to 3.5

[FAQ Index] | [3.5 -> 3.6]

Note: Upgrades are only supported from release to release, it is recommended that you NOT skip releases.

Before upgrading...

To quickly remove all packages from your system:

pkg_delete -q /var/db/pkg/*

The upgrade process may overwrite some X configuration files, you may wish to backup your /etc/X11 directory before upgrading.

Upgrading by install media

Upgrading without install media

Sometimes, one needs to do an upgrade of a machine that 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:

• Place install files in a "good" location. Make sure you have sufficient room!
• Install new kernel(s)

  cd /path
  rm /obsd ; ln /bsd /obsd && cp bsd /nbsd && mv /nbsd /bsd
  cp bsd.rd /
  

  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.
• Reboot on the new kernel
  This might be a tempting step to skip, but it should be done now, as usually, the new kernel will run old userland apps (such as the soon to be important reboot!), but often a new userland will NOT work on the old kernel.
• Stop any applications which might cause problems in the following steps.
• Install new userland applications

  cd /
  tar xzpf /path/base35.tgz
  tar xzpf /path/comp35.tgz
  tar xzpf /path/game35.tgz
  tar xzpf /path/man35.tgz
  tar xzpf /path/misc35.tgz
  tar xzpf /path/xbase35.tgz
  tar xzpf /path/xfont35.tgz
  tar xzpf /path/xserv35.tgz
  tar xzpf /path/xshare35.tgz
  

  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 sets now. Also note that etc35.tgz is NOT unpacked here, as it is handled separately.
• Update /dev. The new MAKEDEV file will be copied to /dev by the installation of base35.tgz, so you simply need to do the following:

  cd /dev
  ./MAKEDEV all
  

  Also see any version-specific notes below.
• Upgrade /etc as below.
• Reboot
