Comment # 20 on bug 1200446 from Ladislav Slez���k

Using "Recommends" will not solve the problem fully, it will only allow using a
workaround and it would introduce just another problems (the repositories might
be missing in the system, I guess these should be always present).

I'm not sure if there is a better solution than the already mentioned AutoYaST
chroot-script.

One possibility is to adapt the openSUSE-release %post script to disable the
repositories if network is not available (or the servers not reachable).

But there is a problem that the network configuration used during AutoYaST
installation can be different than the network configuration used in the
installed system (this is a special AutoYaST feature added on request). So the
network might not be available during openSUSE-release installation but it
might be available later. Or the other way round... :-/
