mount_std, 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 procfs filesystem. A ``standard'' filesystem is one which:
  1. accepts only the standard -o options “ro” (“rdonly”), “rw”, “nodev”, “noexec”, and “nosuid”.
  2. has a kernel filesystem module name the same as its user-visible name.
  3. requires no other special processing on the part of the mount_std command.

The options are as follows:

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 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 procfs(5) manual page for detailed information on this file system.

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.

mount(2), unmount(2), getvfsbyname(3), fstab(5), procfs(5), mount(8)

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.

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