This worked:

--unencrypted-home Fedora-Live-Xfce-x86_64-20-1.__iso /dev/sdc

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,
It will be a few days before I get enough office time to try
this out.

I do believe you are using a later version than me as
"--unencrypted-home" is not supported.

I used the livecd-iso-to-disk that came on the

Fedora-Live-Xfce-x86_64-20-1.iso in the /LiveOS/ directory.

--unencrypted-home only has meaning if you have specified a home.img filesystem for /home through the --home-size-mb option.

It's presence on the command line had no effect.

If it helps with the troubleshooting process, persistence
does work with the "Fedora LiveUSB Creator" GUI. But,
I can only get 4 GB of it.
