The latter. But if it is /dev/sdb you'll likely need to fiddle with
the menu.lst, since when you boot off it in the other machine it'll
probably be /dev/sda (depending on where you put it). 

I'm not aware of a neater way of doing it, this has always sufficed
for me. Boot off the disk in the new machine, edit the command line to
boot off the right disk, then update-grub again so it looks in all the
right places.
