The automounting/autobooting process pays no attention at all th mountlists.
You rdprep your drive telling it the boot priority. This info is read from the
drive during automounting. It is fed to the OS. The OS prioritizes these things
and picks the drive with the highest priority and mounts it. As I noted - the
mountlist is never read for this operation. (This is why the first cylinder is
reserved - all the mountlist stuff and the fastfilesystem executable etc are
stored there in a machine readable format.)
