[CentOS] NFS shutdown issue

Interesting - thanks for the info.  I can understand that behavior in a
shutdown situation.  But I'm surprised that unmounting (either cleanly or
uncleanly) one of two exported filesystems triggers the NFS service to
shutdown completely.  Is this consistent with other peoples experiences?
