mount_memfs --
mount memfs filesystems
Synopsis
mount [-F memfs] [generic_options] [-r] [-o specific_options]
[special|mount_point]
mount [-F memfs] [generic_options] [-r] [-o specific_options]
special mount_point
Description
generic_options are options supported by the generic mount command.
mount
attaches a
memfs
filesystem to the filesystem hierarchy at the
pathname location
mount_point,
which must already exist.
If
mount_point
has any contents prior to the
mount
operation, these remain hidden until the
filesystem is once again unmounted.
The options are:
- -F memfs
-
Specifies the memfs-FSType.
- -o
-
Specify the memfs
filesystem specific options in a comma-separated list.
If invalid options are specified, a warning message
is printed and the invalid options are ignored.
Multiple filesystem-specific options may be listed in any order, but
must be separated by commas.
The following options are available:
- swapmax
-
Maximum amount of memory, in bytes, this mounted filesystem is allowed
to use. Default is the max of an unsigned integer.
- rootmode
-
Specifies the mode of the root directory of the mounted file
system. Default is 0775.
- -r
-
Mount the filesystem read only.
Files
- /etc/mnttab
-
mount table

Notices
If the directory on which a filesystem is to be mounted is a
symbolic link, the filesystem is mounted on
the directory to which the symbolic link refers,
rather than on top of the symbolic link itself.
mount_memfs will set the root mode's owner and group information
to bin, effectively doing a chown and chgrp.
Mounting an memfs filesystem creates an instantiation of the
filesystem.
Therefore, there is no corresponding mkfs command required
for the memfs filesystem type.
