Automatic Unmounting
====================

   To avoid an ever increasing number of filesystem mounts, Amd removes
volume mappings which have not been used recently.  A time-to-live
interval is associated with each mapping and when that expires the
mapping is removed.  When the last reference to a filesystem is removed,
that filesystem is unmounted.  If the unmount fails, for example the
filesystem is still busy, the mapping is re-instated and its
time-to-live interval is extended.  The global default for this grace
period is controlled by the `-w' command-line option (Note: -w.
) or the amd.conf parameter `dismount_interval' (Note:
dismount_interval Parameter).  It is also possible to set this value
on a per-mount basis (Note: opts.).

   Filesystems can be forcefully timed out using the Amq command.
