Allow overriding systemd.user.*.*.Install.WantedBy

[dbeecham]

Description

I have set up gpg-agent.socket, gpg-agent-ssh.socket, gpg-agent-extra.socket, gpg-agent.service and keyboxd.service to all have BindsTo=dev-yubikey.device and After=dev-yubikey.device. I also set up a yubikey.target which Wants all of the sockets and keyboxd, and set up an udev rule to automatically start gpg-agent when I insert my yubikey. This also automatically kills gpg-agent when the yubikey is not inserted.

This helps me immensely, as I have move around between multiple machines constantly, and there are so many cases where gpg-agent will either start automatically as I SSH into a box, or be started automatically when I run git, or anything else on a long list of annoying behaviors.

Currently, the Install.WantedBy field is hard-coded here. A mkDefault in front of [ "sockets.target" ] would make it possible to simply override. That would also not merge the two lists.

Another solution I like is to make the configuration a dependency on DefaultDependencies, as you'd set that if you want to disable autostarting the service anyway.

Install = { WantedBy = mkIf !Unit.DefaultDependencies [ "sockets.target " ]; };

Can you override it with a mkForce ? Or does it still merge the lists?
