Ensure that
the local directory you configure as the mount point is either empty
or nonexistent. If the local directory you configured as the mount
point is not empty, any local files or directories in it are hidden
and become inaccessible if the automounted filesystem is mounted
over it.
Before you can mount a remote directory on a client,
you must configure the remote system where the directory is located,
as an NFS server and you must export the directory.
If you change the mount options, the remote server
name, or the remote directory name for an existing direct or indirect
mount while AutoFS is running, the changes you made take effect
only when the directory is mounted the next time. However, if you
change the local directory name in the direct or indirect map, or
if you change the master map, these changes do not take effect until
you run the automount command to force AutoFS to reread its maps.
