Consider the following points before configuring AutoFS:
Ensure that the local directory you configure as the
mount-point is either empty or non-existent. If the local directory
you configured as the mount-point is not empty, the local files or
directories in it are hidden and become inaccessible if the automounted
filesystem is mounted over the local directory.
Before you mount a remote directory on your system,
you must configure the remote system, where the directory is located,
as an NFS server and export that 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 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.
