I'd concur.

Well, v3 anyway. Anyone know what SCO is using?
This brings up an interesting question as well--will it work over SMB
mounts? I saw No Locks Available references relating to samba on SuSE9
during my searches as well, so I'm curious if SMB/CIFS allows for the
required segment locking.

A long, long time ago I was frightened of it almost literally. Someone
made it out as this incredibly hard to administer subsystem. When I
finally had no choice but to learn it, I about died laughing at the ease of
it all. Anyone willing and able to take their Slackware 1.0 all the way
through a.out->ELF and then libc5->glibc1 -manually- shouldn't really be
phased by NFS. A most delicious irony, since I was still shying away from
NFS after all that.
Last time I listen to anyone when they say a subsystem is difficult. Well,
I hear news is a PITA to administer "correctly", and maybe it is. But
people have said that about email as well, and that's not been the case in
many a year.
But NFS itself, I dunno. Some people cite really poor performance. I have
to wonder if they bothered tuning it--even moderately tweaking it.
