Doesn't rpm have an option like "--inject foobar-1.2.3" that inserts an
entry into the RPM database for package foobar-1.2.3 ?

When I said "can hang indefinitely", I meant "can hang for at least ten
minutes with no sign of *anything* NFS-related happening on client or
server". It wasn't a network traffic thing (3 machines, 100bT switched,
all NICs runing, activity lights on switch all silent.) -o bg wouldn't
have done anything about the root problem, and intr and soft didn't do
anything either (I tried those, no dice.) Recompiling the server's
kernel and switching "NFSv3 support" to N made everything happy.

Things like this seem to happen regularly and are why a popular
expansion of NFS is "Nightmare File System." Various people have been
complaining about Linux's implementation of NFS for a long time now,
though the complaints are usually more like "Linux NFS does not play
well with Solaris NFS".
