Scripted fdisk/slice/fs generation?

Hi all,

I do CPIO style image backups of my FreeBSD systems. In the event that I 
need to restore one of these backups, I usually use the FreeBSD 
installation media to fdisk and create filesystems, then mount the new 
filesystems and restore the CPIO archive.

This system works great for me, but I would like to automate the 
restoration process. I have worked a little with fdisk and disklabel 
back in FreeBSD 2.x days (and trying early versions of OpenBSD) but 
wouldn't really know where to start automating that process. ( I do 
write code, but the thought of trying to use disklabel to read the 
geometry of the disks, calculate sizes, cylinder boundaries, etc give me 
a headache )

I would really like to specify minimum sizes of partitions and 
filesystems, with one having all the excess (rather than having to count 

I've done some searching on Google and havn't really come up with 
anything conclusive.

Can anyone point me in the right direction?
