NAME

       mount_lofs: mount, umount - mount and unmount LOFS file systems

SYNOPSIS


       specific_options] {special_directory|directory}

       specific_options] special_directory directory

       {special_directory|directory}

DESCRIPTION

       The command mounts LOFS file systems.  Only superuser can mount LOFS file systems.  Other users can use to list mounted file systems.

       attaches special_directory, a directory from one of the mounted file systems, to directory, an another directory in one of the mounted file
       systems.  This enables new file systems to be created, which provide access to existing directories or file systems  using  alternate  path
       names.	Both  special_directory and directory should already exist.  directory will become the root of the newly mounted LOFS file system,
       containing the file system hierarchy under special_directory.  special_directory and directory must be specified as  absolute  path  names.
       If  either special_directory or directory is omitted, attempts to determine the missing value from an entry in the file.  can be invoked on
       any removable file system, except

       If is invoked without any arguments, it lists all the mounted file systems from the file system mount table,

       The command unmounts mounted file systems.  Only a superuser can unmount file systems.

   Options (mount)
       recognizes the following options:

	      Attempt to mount all file systems described in
			     All optional fields in must be included and supported.  If is specified, all LOFS file systems in are mounted.  If is
			     specified	in  an	entry's option list, this entry is skipped.  File systems are not necessarily mounted in the order
			     listed in

	      Verbose mode.  Write a message to standard output indicating which file system is being mounted.

	      Specify the LOFS file system type (see
			     fstyp(1M)).

	      Limit actions to local file systems only.
			     LOFS is a local file system.

	      Specify options specific to the LOFS file system type.
			     specific_options is a list of comma separated suboptions and/or keyword/attribute pairs intended for  the	LOFS  spe-
			     cific module of the command.

			     The following specific_options are valid on an LOFS file system:

			     Use all default options.
					    When used, this must be the only option specified.

			     Read-only (see below).

	      Report the list of mounted file systems in the
			     format.

	      Prevent display of error messages
			     resulting from an attempt to mount already mounted file systems.

	      Mount the specified file system as read-only (see
			     below).

	      Report the output in a new style.
			     The  new  style  has  the file system type and flags displayed in addition to the old output.  The directory and spe-
			     cial_directory fields are reversed.

	      Echo the completed command line, but perform no other action.
			     The command line is generated by incorporating the user-specified options and other  information  derived	from  This
			     option allows the user to verify the command line.

   Options (umount)
       The command recognizes the following options:

	      Attempt to unmount all file systems described in
			     All  optional  fields in must be included and supported.  If file system type is specified, all the LOFS file systems
			     in are unmounted.	File systems are not necessarily unmounted in the order listed in

	      Specify the LOFS file system type (see
			     fstyp(1M)).

	      Verbose mode.  Write a message to standard output indicating which file system is being unmounted.

	      Echo the completed command line, but perform no other action.
			     The command line is generated by incorporating the user-specified options and other  information  derived	from  This
			     option allows the user to verify the command line.

EXAMPLES

       Mount an LOFS file system:

       Mount another LOFS file system:

WARNINGS

       LOFS file systems provide the user with numerous applications; however, they may be potentially confusing.  LOFS file systems should gener-
       ally be created by an experienced user.

       For LOFS file systems which are mounted read-only, if the underlying file system is mounted writable, certain write operations on the  LOFS
       will succeed. Thus LOFS should not be relied upon to provide a strictly write-only alternative image of a read-write file system.
