Support for custom systemd units

[castrojo]

It'd be nice if we could have a task for custom systemd units so they can customize the services they need on deplyoment.

Can you give an example of a systemd unit file that you'd want set up? What kind of service do you want started / enabled, etc?

I use a custom service and timer for a flatpak update (I'd rather have the system do this in the background instead of gnome-software). I also enable the anonymous counting via rpm-ostree-countme.timer.

Actually, if there was a centralized place for both flatpak and rpm-ostree updates via #7 I don't think I'd need to run any custom services, though other people might have custom stuff in their setup.
