/etc/auto.master - Master Map for automounter
The auto.master map is consulted when the autofs(8) script is invoked
to set up the necessary mount points for the automounter. Each line in
this file describes a mount point and points to another file describing
the file systems to be mounted under this mountpoint. The access to
those maps is governed by a key.
For indirect automount maps access to an automounted file system is
customarily done using the path scheme:
where the mountpoint will be listed in the auto.master configuration
file. The key is matched in the map file pointed to by the master map
(See autofs(5)). The path and the file are referring to the file on
the file system mounted. For direct automount maps access is via the
full path to the filesystem as given in the associated map. The mount-
point for the direct map is always specified as /- in the auto.master
The file has three fields separated by an arbitrary number of blanks or
tabs. Lines beginning with # are comments. The first field is the mount
point. Second field is the map file to be consulted for this mount-
point. This field is of the form maptype:mapname, where maptype is one
of the supported map types (file, program, yp, nisplus, hesiod,
userdir, ldap), and mapname is the name of the map. The third field is
optional and can contain options to+ be applied to all entries in the
map. Options are cumulative, which is a difference from the behavior of
the SunOS automounter.
The format of the map file and the options are described in autofs(5).
This will generate three mountpoints /home, /misc, and /mnt. All
accesses to /home will lead to the consultation of the map in
/etc/auto.home, all accesses to /misc will consult the map in
/etc/auto.misc, and all accesses to /mnt will consult the NIS map
automount(8), autofs(5), autofs(8).
