       automount - configure mount points for autofs

       automount [options] mount-point map-type[,format] map [map-options]

       The  automount  program  is used to configure a mount point for autofs,
       the inlined Linux automounter.  automount works by taking a base mount-
       point  and  map  file, and using these (combined with other options) to
       automatically mount filesystems within the base mount-point  when  they
       are  accessed in any way.  The filesystems are then autounmounted after
       a period of inactivity.

       -p, --pid-file
              Write the pid of the daemon to the specified file.

       -t, --timeout
              Set the minimum  timeout,  in  seconds,  until  directories  are
              unmounted.   The  default  is 5 minutes.  Setting the timeout to
              zero disables unmounts completely.

       -v, --version
              Display the version number, then exit.

       automount takes at least three arguments.  Mandatory arguments  include
       mount-point,  map-type  and map.  Both mandatory and optional arguments
       are described below.

              Base location for autofs-mounted  filesystems  to  be  attached.
              This is a directory name which must already exist.

              Type  of map used for this invocation of automount.  The follow-
              ing are valid map types:

              file   The map is a regular text file.

                     The map is an executable program, which is passed  a  key
                     on  the  command  line  and returns an entry on stdout if

              yp     The map is a NIS (YP) database.

                     The map is a NIS+ database.

              hesiod The map is a hesiod database  whose  filsys  entries  are
                     used for maps.

              ldap   map  names are of the form [servername:]basedn, where the
                     optional servername is the name of  the  LDAP  server  to
                     query, and basedn is the DN to do a subtree search under.
                     Entries are automount objects in the  specified  subtree,
                     where  the  cn  attribute is the key (the wildcard key is
                     "/"), and the automounterInformation  attribute  contains
                     the  information  used by the automounter.  Documentation
                     on the schema used by this module is available online  at

       format Format of the map data; currently the only formats
              recognized are sun, which is a subset of the Sun automounter map
              format,  and  hesiod, for hesiod filesys entries.  If the format
              is left unspecified, it defaults to sun for all map types except

       map    Location  of  mapfile to use.  This is an absolute UNIX pathname
              in the case for maps of types file or program, and the name of a
              database in the case for maps of type yp, nisplus, or hesiod.

              Any  remaining command line arguments without leading dashes (-)
              are taken as options (-o)  to  mount.   Arguments  with  leading
              dashes are considered options for the maps.

       If  the  automount daemon catches signal USR1, it will unmount all cur-
       rently unused autofs-mounted filesystems and continue  running  (forced
       unmount.)  If it catches signal USR2 it will unmount all unused autofs-
       mounted filesystems and exit if all filesystems were  unmounted.   Busy
       filesystems will not be unmounted.

       autofs(5), mount(8).

       A whole slew of missing desirable features (see TODO file).

       The documentation leaves a lot to be desired.

       Please  report  other  bugs  along with a detailed description to <aut->.  To join this mailing list, send a message  with
