[fedora-arm] Re: User cannot mount USB device - Fedora-Xfce-armhfp-29-20180911.n.0-sda

Peter,

I will test this.

I have a ClearOS6 server with Gnome that I have accessed for years via
VNC and have accessed USB drives all the time.  But that is ClearOS and
their setup, so I may have wrong expectations.  So let's see...

Oh, wait.  I log in as root over VNC to the ClearOS box and that may be way.
