MOUNT_STD(8) BSD System Manager's Manual MOUNT_STD(8) NAME mount_std, mount_devfs, mount_fdescfs, mount_linprocfs, mount_procfs -- mount "standard" file systems SYNOPSIS mount_fsname [-o options] fs mount_point DESCRIPTION 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 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-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) and procfs(5). DIAGNOSTICS argv[0] must end in _fsname The mount_std utility was called with a ze- roth 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.

HISTORY 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.
