I cannot be bothered to do another install.

What I found very off was doing a full install then ending up with a machine 
that will not boot after UDEV, very disconcerting, all because of a missing 
scsi on the startup line.

Why the machine hangs when a scsi card in inserted but not installed I do 
not know.
