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.
