   That shell script was a quite impressing piece of work. Unfortunately
it seems to croak due to the fact that GRUB (I'm using amd64) and cdboot
(Only -current? I'm running NetBSD/amd64 3.0) are missing. Am I out of lu=

   :-) The problem is that I'm also going to resize the partitions while
moving them around which makes dd a little too tricky for me.
dump/restore seem to be exactly what I'm looking for. Thanks!

   My kind of boot CD! I'll give it a try!
