    Who said anything about an internet connection?  Would you do NFS over the
internet?  In any shop that is considering getting the machine up "fast" the
quickest way would be to get the bare system on, throw it on the network, and
either mount a drive over NFS or FTP.  At least, that is how we did things in
the shop I was in.

    Of course now we just have master disks for everything, we just dupe the
disk and drop the data in off backup.  Takes us ~1/2 hour to replace a machine
and get it back up and running with the previous configuration.

    2Gb for the programs which are stored on a varity of different media or
2Gb for the data.  I'd rather have 2Gb of data, thanks.

    File a bug on it, then.  I would like to see that to having lost /usr once
on my server at home.

    Depends on what you have on there.  If it is stuff that is easily replaced
from source, recompile.  I'd backup the sources, not the programs themselves.
