The following patch fixes an oops that will occur if root kills
off the rpciod daemon while an NFS partition is mounted, and then
somebody proceeds to write to that partition.
This is mainly a 'problem' for people who use nfsroot together with
the 'halt/reboot' scripts in the RedHat distribution. They perform a
'kill -9 -1' right before they write the shutdown message to the wtmp
file.
Everybody else can safely ignore this patch.
Cheers,
Trond
