Re: Cached file system -- summary and /usr [second attempt]

A number of people, among them
   ross@bio-medical-physics.aberdeen.ac.uk
   casper@fwi.uva.nl
   caywood@teb.larc.nasa.gov
have commented the possibility to cache-mount /usr. Like them I have
also found that it works with the -O option to mount. It was also
mentioned that this should be done as early as possible in the boot
process.

Provided this question is properly solved I would like to discuss the
following:

Assume a network with one main server and a reasonable number (10 - 20) of
workstations. They have local disks ranging from 100M to 400M. All
user files reside on the server. I suggest that all workstations
should be dataless with the entire free local space taken up by a
cache filesystem, caching /usr, any local software, and home directories.
This way each workstation would automatically get the files _it_ uses.
It would mean a slow system the first few days, but that should be acceptable.

Comments?
Leif
