I understand your position. What I don't understand is what you are
suggesting. What are you suggesting should change in Devuan? Are you
suggesting that daemon monitoring be included and activated by default?

It sounds like to me that you as a developer of custom software have a
solution that works well for you. Does that have anything to do with
monitoring services and restarting them on Devuan? Are you just anxious
to show the other side of the coin that automatic restarts are useful in
some cases? Because, AFAICT, that is NOT what is being discussed.

I am not the author of apache. So I am not going to make assumptions
about when it can or cannot be automatically restarted safely.

I know cpanel and WHM have something to handle restarting crashed
services. I think that someone, who needs that hand holding, not use a
general purpose OS - which Devuan is striving to be. Am I mistaken?
