Option to restart applications if method known

[tsujamin]

For machines that run automatic security updates, it would be useful if tracer were configurable to execute service restarts for daemons it knows about. This could be enabled by a command line switch, or a configuration file for the dnf-plugin (with white listing of particular packages).

Not sure if this is a function you see tracer fulfilling, but I might hack on it a bit if I find some time.

I personally haven't needed this, but I agree that it can be nice in some scenarios. Feel free to send PR if you want to code it by yourself :-). Or I will do it, but it can take some while.

I've started on an implementation (https://github.com/tsujamin/tracer) which adds a new Controller/View for restarting services and the commandline flags "--restart-daemons" and "--restart-services"

I've tried to mock up some unit tests for the controller, which appear to pass, but I haven't really been able to test it in practice as I don't have any daemons that need restarting ;) How should I go about testing this properly?

I'll probably look into integrating this with the dnf-plugin, but it appears that's in a separate project at the moment. If it were to go that far, being able to enable/disable the functionality and blacklist certain packages from automatic restarts would be something I'd look to implement (probably with ConfigParser or something similar), but I figured I'd run this past you before going any further :)

FWIW, while waiting on this feature I implemented an alternative stale-process-checker that supports automatic restarts via --restart: https://github.com/gsauthof/utility/#oldprocs

Ah, I am sorry, I somehow missed the comment. I guess it's not
relevant anymore.

Perhaps I should add a section with known alternatives to the README
section and mention your tool?

Also, if you don't mind, I would keep this issue open. It's a valid
RFE.

Sure, adding a section that puts a project into perspective like that usually is a good idea.

@gsauthof I added a Similar software section to the README in b390877, feel free to edit it or list other alternatives.
