The *point* of the copy-and-edit system is so the 'stock' configuration
can be updated and you don't wind up with .rpmnews all over the place.
If we ship it as /etc/systemd/system/vncserver@.service and you edit it,
it's never going to be 'magically' reconciled on update, you'll just get
a .rpmnew file. That's not any better.
Things could still change behind your back and make your /etc/sysconfig
file not work any more in the old system...
