[systemd-devel] Adding a Timer section to .service files

[Michał Zegan]

Well, I also came with another idea. of course if you do not want to
have two different ways to do one thing it is a stopper, but I will tell
about it for completeness as it may or may not be easier to implement.
Instead of creating a timer unit on service file installation or
something, you could have service and similar sections in the timer
unit, so the other way around. then, if service name is not explicitly
set in the unit and the service file with appropriate name does not
exist, it could just create it using information found in the timer unit
file, if such information can be found. The service file will be
generated in /run/systemd/system for example and it will work normally.
So, except the reason about not wanting to have two different ways of
doing one thing, it does not have other problems of the approach
mentioned first unless you also have another reasons not to generate
service units this way.
