I don't think you really want to. Years ago I setup a diskless linux cluster where all the disk space was served from a common server. At that time what I came up with was a mounted root unique to each client with less than 15MB per client. They all mounted the same /usr and /home partitions, but had there own / with configurations and /var & /tmp. The unique partition for each was actually a copy of one of them, they just each had exclusive access to modify it without clobbering the others. Our cluster booted off of a floppy and then mounted root as nfs. If you put CDROM's in the clients you might be able to do the same thing but use a large ramdisk for the unique roots. If you really need to not have unique roots the only way I can think of is using a ramdisk for the clients and them mount your common file systems. -------------------------------------------------------------- Robert E.
