You should be able to do it all from beofdisk.  What are you doing
between the 'beofdisk -q' and 'beofdisk -w' ?  I recommend running
'beofdisk -d' to get a good default partition layout, then doing
'beofdisk -w' to write it to the disks.

You should have commented this out.  Having two different partitions
you're trying to mount as / is a Bad Thing (tm).

You really don't have to mount this partition.  It is written by
beoboot-install which doesn't need it mounted, and only read during
boot.  Also, the fact that you didn't start 'beoboot' with a / is
causing the node_up script to not create a mountpoint for it, which is
causing the maount failure you described.  I recommend just removing
this line.

All of that should be fine, assuming you actually wrote a partition
table to your disk with the partitions you listed here.
