[systemd-devel] Can /usr/lib/systemd/user/sockets.target.wants be used to autoenable a socket by a vendor package?

Good point. When I symlink it into
/usr/lib/systemd/user/default.target.wants it starts on boot.

Also, I've created a simple perl server:

https://gist.github.com/x-yuri/45f53c16a99337ba0716a988290491bd

And if I put perl-server.socket and perl-server.service into
/usr/lib/systemd/user, and symlink perl-server.socket into
/usr/lib/systemd/user/sockets.target.wants, it autoactivates on boot.

The confusing thing though is:

$ systemctl --user is-enabled perl-server.socket
disabled

And the fact that enable/preset/disable create/remove symlinks in
~/.config/systemd/user/sockets.target.wants.

Which doesn't happen with a service (e.g. infinite-tsukuyomi) when the
service is in /usr/lib/systemd/user.
