How is gpg-agent being _started_?  Is it systemd?

If so, go to <https://public-packages.pennock.tech/> and scroll down to
"Users of systemd with vendor-installed socket activation of gpg-agent
will have to weigh their options carefully" neat the bottom; it's one of
the bullet points for the `optgnupg-gnupg` package.  It talks about how
to change the gpg-agent which systemd will launch for you.

Those are the steps I use on an Ubuntu system to swap out
/usr/bin/gpg-agent in favour of /opt/gnupg/bin/gpg-agent.
