NAME
/etc/auto.master - Master Map for automounter
DESCRIPTION
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:
/mountpoint/key/path/file,
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
map.
FORMAT
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 without a leading dash are passed on (with -o) to the
mount command. Those options preceded by a dash are considered map
options. Options can be separated by commas or spaces. For example:
/home /etc/auto.home ro,intr -DOSREL=3.0E
The option string "-o hard,intr" is passed to the mount command for
each of the entries in the auto.home map. The option "-DOSREL=3.0E"
is parsed by the map format specific parser.
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).
EXAMPLE
/home /etc/auto.home
/misc /etc/auto.misc
/mnt yp:mnt.map
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
mnt.map.
