According to its manual page, automount "manage[s] autofs mount points." It runs at startup and "sets up mount points for each entry in the master map, allowing them to be automatically mounted when accessed." autofs is the service program that does the mounting/unmounting when needed.
Server Configuration
An NFS server must list the directories it serves in /etc/exports.
General Configuration
automount looks in /etc/auto.master for a map. Our setup apparently requires a non-default mapping:
/net /etc/auto.net
It is important to note that that is not the default /etc/auto.net either. The detailed contents of auto.master and auto.net can be found here: Autofs Configuration Files.
If SELinux is enabled, once the files are added/edited, their security context may get changed as well, and it may be necessary to run restorecon -R -v /etc before restarting autofs, in order for autofs to work.
Backup Server Configuration
In addition to the above changes, the backup server has the line
/mnt/npg-daily /etc/auto.npg-daily
in /etc/auto.master, and
# mount backup disks by label * -fstype=auto,noatime :-Lnpg-daily-&
in /etc/auto.npg-daily . The '*' is for matching, and the '&' gets replaced by what is matched. So, for example, a search for "30" will mount the drive labelled "npg-daily-30". See the manual for autofs for more details.
