NAME    [Toc]    [Back]

     mount_std, mount_devfs, mount_fdescfs, mount_linprocfs, mount_procfs --
     mount ``standard'' file systems

SYNOPSIS    [Toc]    [Back]

     mount_fsname [-o options] fs mount_point

DESCRIPTION    [Toc]    [Back]

     The mount_std utility is a generic mechanism for attaching ``standard''
     file systems to the file system.  The mount_std utility currently supports
 the following file systems: devfs, fdescfs, linprocfs and procfs.
     A ``standard'' file system is one which:

	   1.	accepts only the standard -o options ``ro'', ``rw'',
		``nodev'', ``noexec'', ``nosuid'', and ``union''.

	   2.	has a kernel file system module name the same as its user-visible

	   3.	requires no other special processing on the part of the
		mount_std utility.

     The options are as follows:

     -o      Options are specified with a -o flag followed by a comma separated
 string of options.  See the mount(8) man page for possible
	     options and their meanings.

     The mount_std utility examines its zeroth command-line argument (the name
     by which it was called) to determine the type of file system to be
     mounted.  If it is called by a name which does not end in ``_fsname'',
     mount_std will assume (for compatibility with mount(8)) that the zeroth
     argument contains only the name of the file system type.  The mount_std
     utility is normally installed with appropriate links to commands for the
     distributed file systems which can be mounted in this way; for information
 on the function of each file system, see the manual page for that
     specific mount_fsname utility.

     Refer to the following manual pages for detailed information on these
     file system: devfs(5), fdescfs(5), linprocfs(5) and procfs(5).

DIAGNOSTICS    [Toc]    [Back]

     argv[0] must end in _fsname  The mount_std utility was called with a
     zeroth argument of ``mount_std''.

     %s file system not available  The specified file system type was not
     present in the kernel and no loadable module for it was found.

     None of the ``standard'' file systems may be NFS-exported.

HISTORY    [Toc]    [Back]

     The mount_std utility first appeared in FreeBSD 2.2.  Loadable file system
 modules first appeared in FreeBSD 2.0.  The ``fdescfs'' and
     ``procfs'' file system types first appeared in FreeBSD 2.0; the ``devfs''
     file system type first appeared in FreeBSD 2.2; the ``linprocfs'' file
     system type first appeared in FreeBSD 4.0.
