Persistence works for me.
Check dmsetup status
and
dmsetup table
See that the live-rw snapshot has been set up on a loop device backed by
the overlay file
and not a temporary overlay, which would be the fallback if no overlay
was found or it
was unreadable.

If you don't get similar results, check the system journal for errors on
the filesystem.
Hi Fred,
Thank you for helping me with this.
From the host machine ("#" is root's prompt):
>>> note that our versions don't match <<<
I am at the mercy of EPEL. They will update to
the latest version when they do and not a moment
sooner.
Also note that persistence works fine with "liveusb-creator"
(the GUI), but that you can not get more than 4 GB
of persistence.
