.Nm Newfs

Before running
.Nm

.Nm mount_mfs ,
the disk must be labeled using

.Nm Mount_mfs
is used to build a file system in virtual memory and then mount it
on a specified node.
.Nm Mount_mfs
exits and the contents of the file system are lost
when the file system is unmounted.
If
.Nm mount_mfs
is sent a signal while running,
for example during system shutdown,
it will attempt to unmount its
corresponding file system.
The parameters to
.Nm mount_mfs
are the same as those to
.Nm .
If the
.Fl T
flag is specified (see below), the special file is unused.
Otherwise, it is only used to read the disk label which provides
a set of configuration parameters for the memory based file system.
The special file is typically that of the primary swap area,
since that is where the file system will be backed up when
free memory gets low and the memory supporting
the file system has to be paged.
