Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

Right now, I am specifying repositories to be used for installation in the kickstart file via the repo directive. I am then, re-specifying those repositories to be added to the /etc/yum.repos.d post-installation.

Is there an elegant way to avoid the duplication of information? It has bitten me in the butt once already.

Clarification:

Perhaps I am understanding this incorrectly but: it seems that the repo directive is only used for specifying the repositories that are used by anaconda for installation. It does not actually install the repo on the server. I'm basing this presumption on my experience with kickstart installs.

This is why I install the repositories again post-install. I want to know if there is a better way so I do not have to specify the repositories in both the repo directive and in my post-install script.

In the post section of your kickstart include something like this:

%post
cat >/etc/yum.repos.d/your.repo <<EOF
[... INCLUDE REPO CONFIG FILE CONTENTS HERE ...]
EOF

Definitely, see updated answer. –  Andrew Case Sep 25 '11 at 18:36

Just like the definition of the installation repo this has to be done twice. We use a postinstall-script that gets called in the %post-section. That script in turn copies the appropriate repo-files to /etc/yum.repos.d/ - depending on the os.

That way we use almost the same kickstart file for CentOS 4 and CentOS 5.

I know this is an old thread, but as I found another (likely added in a later version of cobbler) solution, I thought I'd add it:

If you put $yum_config_stanza in your %post in your kickstart templates cobbler will create a .repo file of the assigned repos and place it in /etc/yum.repos.d/ for you. I also remove the default ones so that only my mirrors are used.

The relevant part of my kickstart template:

%post --log=/root/ks-post.log

#configure repos
rm /etc/yum.repos.d/*
$yum_config_stanza
