AUTO.MASTER(5)                File Formats Manual               AUTO.MASTER(5)



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 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.
