Simply, you can mount each mount point with the fstab file and a
script, same approach of every linux distribution, nothing more. Even
in the pc world you can mount your /home on a partition with ext3,
/var in a partition with ext4, and so on. A very simple approach to
setup the system, it is to start with NFS for example with "whole" fs,
copy what you need in the right place, setup the start-up script and
reboot.
