Julian Elischer has volunteered to commit the patches that
make the -S option the default for mountd.

Without this option, any reload of /etc/exports (which happens
whenever any file system is mounted on the server) can result in
error replies to NFS clients, due to the file system being temporarily
not exported. The only downside I can think of to using this option
is a delay observed by NFS clients when large /etc/exports files
are reloaded. (Since without the delay they can get error replies,
the delay seems preferable.

There are several PR#s related to these error replies:
9619, 131342, 206855 (and probably some others)

If anyone has a problem with this change in default behaviour,
please email.
