reboot after installation fails

We have an Xserve that is only running Linux, so we're in the same boat.
And it's running just great.

As far as I can see, the reason for the failure was your removal of the
Mac special partitions.  A Mac will not boot at all without them.  Boot
Mac OS X from the CD, install it, and then boot from the YDL CD.  You
can take out the Mac OS X partition, but you must leave the Mac
partitions 1-8 as indicated below (partition map from our machine):

# pdisk -l /dev/hde

Partition map (with 512 byte blocks) on '/dev/hde'

YDL doesn't need Mac OS, but the machine itself won't boot unless you
have these partitions left.  Note that there is no Mac OS on any of
these partitions.
