Yep, it's purely a configuration of hte Cobbler server thing. If the
client still tries to netboot, it should just timeout/failover (but
requires client configuration on the ordering, etc.).

Yes, that does seem like a good option. As I mentioned, I think to test
it, it  should be straightforward to use a trigger, and then someone
could open an issue/work on a code-fix (probably needs a configuration
entry, etc.).
