Is there something that can be done "on-line" to de-fragment Unix partitions?
Or is the best bet to just backup and restore the partition using something
other than 'dump'?  My /usr partition is at 6% fragmentation (according to
fsck) -- The system has only been up for a couple of months, and I've been
getting usenet news for a few weeks.  That seems like a lot for such a short
time.  I'm using the Esix ffs.  (I haven't done anything with the Esix
"2K file system utility" yet -- I'm not sure what is on that disk-- been too
busy to experiment...)
