And don't bother to read -hackers.

People who think this is about NFS mounting only have obviously not read
the README on the sire Martin supplied. I urge a person who bothers to
comment on this, should read the README first and [politely] discuss any
points with Martin on this list.

For all I know about this subject I can at least say I like the proposed
sanity-checks. Sanity-checking is something we can always use.
