system cloning

[Tony Shadwick]

You expect too much of my RAID controller. :) Ghost won't do it because:

1.  There is only room for 3 drives in the system.  RAID5 requires 3 
drives.

2.  Ghost deals in partitions.  FreeBSD (usually) has one partition with 
many slices.

3.  Doubt it has drivers for my RAID array. :)
