a pointer to the direct, indirect, and built-in maps that
automount is to use.
the mount point for each indirect and built-in map listed in this master
map.
optionally, mount options that apply to all mounts in each map
listed in this master map.
By default, automount looks for an NIS master map
named auto.master when it starts up.
Options to the automount command can direct automount to
use a local master map (-f option) or
ignore the NIS master map (-m option).
If a local master map is specified with the -f option and the
-m option is not specified, automount reads
both master maps,
but entries in the local master map have priority if duplicates
between the two master maps occur.
The names of direct, indirect, and built-in maps can be
passed as arguments to the automount command in lieu of or
in addition to using a master map.
Each line in the master map (by convention called
/etc/auto.master) has the syntax:
mount_point map_name [ mount_options ]
mount_point
May be either a full pathname or the string ``/-''.
A full pathname tells automount that the map-name field value
is the name of an indirect map or a built-in map.
Whether an indirect or built-in map is used,
automount uses the pathname to build
the mount point
on which automount is to mount the filesystems listed in the map.
If any of the directories in the pathname do not exist, automount
creates them, if possible. If the basename directory exists and is
not empty, mounting on it hides its contents.
automount issues a warning message in this case.
The string ``/-'' tells automount that the map-name
field value is the name of a direct map that automount is to read
for filesystems to mount.
map_name
Is the name of a direct, indirect, or built-in map.
mount_options
Is an optional list of options (separated by commas)
that regulate the mounting of the entries
mentioned in map_name, unless the entries in
map_name list other options. Mount options
listed in a direct or indirect map override options listed here.
You may specify options here that are defined for NFS-type
mounts in the
mount(ADM)
reference manual page, excluding bg (background) and
fg (foreground), which do not apply.
