Setting up vncserver was easy.  The only thing to note is that the 
xstartup is for gnome.  Change as follows for Xfce:

# exec /etc/X11/xinit/xinitrc
exec  /bin/sh /etc/xdg/xfce4/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
startxfce4 &

You have to first start vncserver so that you get the gnome xstartup 
file.  Then you edit it, stop vncserver, and restart it.  Very 
challenging.  See my bug: 633811

With no screensaver, the session never locks.  I went away for a 
doctor's appt and came back 2 hours later and still had the open, 
unlocked, vnc session.  Of course my notebook's desktop was locked.

I inserted a usb drive, and when I went to mount it, it polkit dialog 
asked for my password.  My user account is in group wheel.  I installed 
k3b, attached a usb CD/DVD writer, but k3b did not 'see' /dev/sr0 and 
threw an error.  These are selinux policy issues that I don't know how 
to adjust.

Anyway, I am putting Centos-arm work away and going back to Nethserver 
(which is still Centos-arm) until Pablo is able to make the necessary DE 
group(s).  Or someone else much more skilled than I.

And thanks Pablo for getting it this far along!
