The mount_std command is a generic mechanism for attaching ``standard''
filesystems to the filesystem. The mount_std command currently supports
the following filesystems: linprocfs and procfs. A ``standard'' filesys-
tem is one which:
1. accepts only the standard -o options ``ro'' (``rdonly''),
``rw'', ``nodev'', ``noexec'', ``nosuid'', and ``union''.
2. has a kernel filesystem module name the same as its user-visi-
3. requires no other special processing on the part of the
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 command examines its zeroth command-line argument (the name
by which it was called) to determine the type of filesystem 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 filesystem type. The mount_std
command is normally installed with appropriate links to commands for the
distributed filesystems which can be mounted in this way; for information
on the function of each filesystem, see the manual page for that specific
Refer to the following manual pages for detailed information on these
file system: linprocfs(5) and procfs(5).

the %s filesystem type.

present in the kernel and no loadable module for it was found.

The mount_std utility first appeared in FreeBSD 2.2. Loadable filesystem
modules first appeared in FreeBSD 2.0. The ``procfs'' filesystem type
first appeared in FreeBSD 2.0; the ``linprocfs'' filesystem type first
appeared in FreeBSD 4.0.
None of the ``standard'' filesystems may be NFS-exported.
