-
-1: This value means that PMFS will not be loaded from the backing file during

-The above example assumes that there is a PMFS already present at the specified
-physical address (create during an earlier mount). It uses that same PMFS
-instead of loading it from /data/pmfs.img. It, however, saves the file system
-to /data/pmfs.img during unmount.
