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 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
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 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).
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.
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.
