I'm not sure I'd agree that it is better/cleaner to restart the daemon.

There may be some corner cases where the dynamic config stuff doesn't
let you do/undo everything - in that case it would be better to find and
fix these cases.

Most folks have a strong preference for letting ntpd run for as long as
possible.  And I think you'll find that there can be a lot to do to
"undo" everything that is in-place just to cleanly re-process an
ntp.conf file.

Have you tried running those commands from the ntpq CLI, with the
:config directive?

I also don't know if anybody has written a test case for the
config-from-file stuff.  That might be a good place to start - you can
use the 'saveconfig' directive to test to see if your changes have been
made.

Please consider discussing your ideas with folks - you are looking at a
lot of work and if you want to see your patches included in the main
distribution it would be best if we all agreed on how things look.
