NAME

       automount - configure mount points for autofs

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       -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 dis-
	      ables unmounts completely.

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

ARGUMENTS

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

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

       map-type
	      Type of map used for this invocation of automount.  The following are valid map types:

	      file   The map is a regular text file.

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

	      yp     The map is a NIS (YP) database.

	      nisplus
		     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	http://docs.iplanet.com/docs/manu-
		     als/directory/411ext/nis/mapping.htm.

       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 hesiod.

       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.

       options
	      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.

NOTES

       If the automount daemon catches signal USR1, it will unmount all currently 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.

BUGS

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

       The documentation leaves a lot to be desired.
