mount_memfs.1m (2010 09)

m
mount_memfs(1M) mount_memfs(1M)
ninode=nnis the maximum number of files that can be created on the file system.
If n is 0 or the option is not specified, the number of files is not restricted,
though it is limited by the available memory for MemFS, as specified by
the memfs_metamax
tunable (see memfs_metamax(5)).
mode=mode
Permissions to be set for the root of the file system after mounting, can be
specified using octal number only. Permission can be logical OR (sum) of
following mode bits:
0400 Read by owner
0200 Write by owner
0100 Execute (search in directory) by owner
0040 Read by group
0020 Write by group
0010 Execute/search by group
0004 Read by others
0002 Write by others
0001 Execute/search by others
By default, permissions will be set to 0755.
user=user The user ID or login name found in /etc/passwd, to be the owner of the
root of the file system after mount. By default, owner will be set to root.
group=group
The group ID or group name found in /etc/group, to be the owning
group of the root of the file system after mount. By default, group will be
set to root.
remount Changes the mount options for a mounted file system. Only size and
ninode can be modified by remounting the file system. To switch the file
system to have unlimited size or number of inodes, 0 has to be used as the
argument. Use chmod and chown to modify the permissions and owner
of the root respectively. See chmod(1) and chown(1).
suid Allow set-user-ID execution (default).
nosuid Do not allow set-user-ID execution.
-p Report the list of mounted file systems in the /etc/fstab format.
-Q Prevent the display of error messages resulting from an attempt to mount already
mounted file systems.
-v Report the regular output with file system type and flags; however, directory and spe-
cial fields are reversed. The special field for
memfs always contains the text memfs.
-V Echo the completed command line, but performs no other action. The command line is
generated by incorporating the user-specified options and other information derived
from /etc/fstab. This option allows the user to verify the command line.
Options (umount)
umount recognizes the following options:
-a Attempt to unmount all file systems described in /etc/mnttab. All optional fields in
/etc/mnttab must be included and supported. If -F memfs is specified, all MemFS
file systems in /etc/mnttab are unmounted. File systems are not necessarily
unmounted in the order listed in /etc/mnttab.
-F memfs Specify the MemFS file system type (see fstyp (1M)).
-v Verbose mode. Write a message to standard output indicating which file system is
being unmounted.
-V Echo the completed command line, but performs no other action. The command line is
generated by incorporating the user-specified options and other information derived
from /etc/fstab. This option allows the user to verify the command line.
