Each diskless client should have its own root and swap partition. On your
server, create one or more disk partitions large enough to hold all of the
roots your clients need. It should be /export/roots.  Now in this
partition, create subdirectories for each client, usually naming the
subdir the name the client machine.  Now you export each subdirectory with
a seperate line in your exports file.
