I found out what's causing this issue. It's by design :)

FAI detects it's running from cd, so it ejects the cd from the cd-rom 
player, and waits for user input. However, I'm running from a 
recoverydisk partition (copied the iso to it on first install), and want 
it to reboot automatically. So, I made a new script, which does:


FAI will not detect it's running from cd anymore, and reboot itself.

...Now the question is: is this safe? Or is RUNNING_FROM_FAICD used for 
other stuff? I know that when it's not there during the install, FAI 
will not mount the cd and try to run from nfs. But deleting the file at 
the end of the install seems to circumvent this.

With kind regards,
