run liveCD on system B, make partitions as you like, newfs, mount as 
needed under say /mnt (like /mnt, /mnt/usr etc), set up network and do

cd /mnt
rsh -l root IP_of_systemA "tar --one-file-system -cf - / /usr /othermountpoint /anothermointpoint"|tar xpf -
cd /
umount /mnt

make sure you did

bsdlabel -B yourfirstdrive

on systema activate rshd and add ip of systemb to .rhosts in /root, at 
least temporarily.

keep machines in sync with rsync, prepare your rsync script, exclude list 
etc etc.
