Guide to Unix/BSD/OpenBSD/Customize Installation

You may want to customize your installation if:

• you want to install a new set of packages during the OpenBSD installation.
• if you want to report an installation problem.
• If you want to change the default configuration files.

Inside the iso

Mount the iso and cd into it. See the Guide to Unix Explanation section on how to mount an iso file. Then the <your OpenBSD release>, and then <your processor> directory.

cd /<where the mounted iso is located>/<your OpenBSD release>/<your processor>

For me it is:

cd /Volumes/OpenBSD:i386_4.4_Install_CD/4.4/i386

(My auto-mount system gives the files that it mounts long names).

Layout

For OpenBSD 4.4 i386 it is:

4.4
   i386
      BASE44.tgz
      boot.catalog
      bsd
      bsd.mp
      bsd.rd
      cdboot
      cdbr
      comp44.tgz
      etc44.tgz
      game44.tgz
      man44.tgz
      misc44.tgz
      xbase44.tgz
      xetc44.tgz
      xfont44.tgz
      xserv44.tgz
      xshare44.tgz
      TRANS.TBL
   TRANS.TBL
etc.
TRANS.TBL
   boot.conf
   TRANS.TBL

Customize

Take the packages out of the iso and edit them as described below. Then take all of the files and make a new iso.

Install additional packages

Cd into the iso as directed before. Now change the file permissions. If you want another package installed as an option. Take the package and rename it (do not put a period):

site<your version>-<the package name>.tgz

For abiword on OpenBSD 4.4, it is:

site44-abiword.tgz

You will also have to find its dependencies and include them as well.

Change configuration files

Untar etc44.tgz. You will find all of the default configuration files in etc. inside of the package. Edit them and retar them.
