Or activate/desactivate.

But whatever the name, there is going to be some ugly interactions with
enable/disable. (We would want desactivate to match globs too in order to
be able to desactivate older instances, but then how do we check which has
precedence between enable/disable/activate/desactivate).

Maybe it is instead way easier to just directly call systemctl enable.
Still, one feature missing is the ability to desactivate all services files
(systemctl preset-all leaves the instances alone even with a disable *) in
order to go back to a 'pristine' state from which one can call systemctl
preset-all and then enable the instances.
