Not sure about that - I think all that matters is that the things in 
fstab can actually be mounted.  There is some trick to installing grub 
on a disk that is going to be moved to a new position that I've 
forgotten, though.  But you can boot the install disk in rescue mode to 
fix that if you get it wrong.
