Re: terminalserver and added packages

That's what I do with ParallelKnoppix, the NFS shared working dir is
mounted on all hosts through a line in knoppix.sh. In the same way,
the clients could mount anything else that has been exported. But the
details need to be worked out. It seems like exporting a compressed
image might work, at least as long as there is no dynamic information
that would need to be synced between hosts.
Thanks for the feedback, Michael

That's the idea, yes, so the data that's actually transferred over NFS
is still compressed, and gets uncompressed on demand on the clients.
This saves a lot of bandwidth, and makes use of of the CD block cache on
the server for faster access.

I haven't thought about that possibility yet, though I think this could
be done by using the knoppix.sh feature for mounting file systems

Problem: unionfs gets REALLY unstable over NFS. So, we would need a
different solution. Maybe another branch exported as compressed image,
and unionfs-mounted on the client.
