mount_std, mount_fdesc, mount_linprocfs, mount_procfs -- mount ``standard'' filesystems


mount_fsname [-o options] fs mount_point


The mount_std command is a generic mechanism for attaching ``standard'' filesystems to the filesystem. The mount_std command currently supports the following filesystems: fdesc, linprocfs and procfs. A ``standard'' filesystem 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- ble name. 3. requires no other special processing on the part of the mount_std command. 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 mount_fsname command. Refer to the following manual pages for detailed information on these file system: fdesc(5), linprocfs(5) and procfs(5).


argv[0] must end in _fsname Mount_std was called with a zeroth argument of ``mount_std''. vfsload(%s) Mount_std was unable to load a kernel module implementing the %s filesystem type. %s filesystem not available The specified filesystem type was not 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 ``fdesc'' and ``procfs'' filesystem types 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. DragonFly 4.1 July 5, 2012 DragonFly 4.1
