The help with the miniroot and the disk partioning has been very usefull. 
The reason I was asking about the mount command and partioning is because 
I guess the miniroot, when given as the root_device is mounted 
read-only.  I have tried to mount other drives, but because the 
root_device is read-only I can't make a directory fot the mountpoint, and 
when I try to use on of the other directories the mount command return 
the message:
mount: exec: mount_ffs no command for /a:

any help on how to make the miniroot accept mounts.

thanx
