MOUNT_STD(8)            FreeBSD System Manager's Manual           MOUNT_STD(8)

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

     mount_fsname [-o options] fs mount_point

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

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

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

           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 sepa-
             rated 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 informa-
     tion 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), linsysfs(5) and

     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.

     mount(2), unmount(2), getvfsbyname(3), devfs(5), fdescfs(5), fstab(5),
     linprocfs(5), linsysfs(5), procfs(5), mount(8)

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

     The mount_std utility first appeared in FreeBSD 2.2.  Loadable file sys-
     tem 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.

FreeBSD 6.2                    November 26, 2004                   FreeBSD 6.2
