Another alternative is to automount on demand (man 5 autofs), though there
are some issues with that (e.g. sometimes /etc/mtab is updated so autofs
thinks its mounted but it really isn't).  Clean shutdown is also somewhat
of a problem, especially with IB (e.g. openibd won't unload if its in use
by Lustre).
