Really? if you want a UI that controls whether NTP server software is
running, why not call into the EnableUnitFiles() APIs directly?

Also, if you want timedated to be a frontend for configuring *server*
software, will you add another tool next, for controlling a HTTP

I am sorry, but timedated is really not the place to control NTP
*server* software. It's simply, desktopy stuff, for controlling NTP
clients. And if you install a full NTP server, then the NTP client
already gets kicked out of the initil transaction and all is good. 

The way to configure server software is via "systemctl enable" and
"systemctl disable" not via "timedatectl".
