in my experience, NFS on linux is ****ing awfull.  if it bothered me
enough, i might be motivated todo somethign about it.  but it doesnt.

you could always use a network FS that does work.  like that lovely
windows reverse engineered program, smb.


hmm, maybe i'm being harsh.  linux NFS client acess works most of the
time.  server side is a joke.  but hey, we have the source code, so lets
just ignore it, until someone else fixes it, or implements a decent
replacement.

BTW, on a less agressive note, tcpdump, strace and lsof are always your
friends.

there are several things under linux which IMNSHO suck, NFS is somewhere
near the top of by shooting spree agenda.
