Arch Linux

Description: This one is probably questionable, but if you don't known much about gpg, and, to top it off, the gnupg home is not in ~/.gnupg (in which case socket activation won't work), this might be confusing.

As things stand:

$ systemctl --user is-enabled dirmngr.socket
disabled

Which is confusing. But if you delete the [Install] section:

$ systemctl --user is-enabled dirmngr.socket
static

Which makes sense. This happens because enable/disable/is-enabled concern themselves only with ~/.config/systemd and /etc/systemd:

https://lists.freedesktop.org/archives/systemd-devel/2022-September/048338.html

Putting the symlinks into /usr/lib/systemd for units with [Install] sections is like providing a way to enable the units twice.

One way to solve this is copy the units into the arch repo.

Another:

$ cat doc/examples/systemd-user/dirmngr.socket | sed '/\[Install\]/,$d'

You can also delete the last empty line if you will:

$ cat doc/examples/systemd-user/dirmngr.socket | sed '/\[Install\]/,$d' | sed '$d'

But this way it may break one day. No good solution.
