-This option sets the overlay size in mebibytes (integer values only).  The overlay makes
persistent storage available to the live operating system, if the operating system
supports it.  The persistent LiveOS overlay holds image-change snapshots (using
write-once, difference-tracking  storage) in the /LiveOS/overlay-<device_id> file,
which, *one should note*, always grows in size due to the storage mechanism.  (The
fraction of allocated space that has been consumed may be displayed by issuing the
'dmsetup status' command in a terminal session of a running LiveOS installation.) 
One way to conserve the unrecoverable, overlay file space, is to specify a persistent home
folder for user files, see --home-size-mb below.  The target storage device must have
enough free space for the image and the overlay.  A maximum <size> of 2047 MiB is
permitted for vfat-formatted devices.  If there is insufficient room on your device, you
