Subject: TTY Auto-login is not compatible with elogind
Date: Thu, 11 Jan 2024 13:46:32 +0100

Enabling both TTY auto-login and elogind-service-type at the same time
results in an error immediately after automatic login to the tty with
the message "Error in service module", and the TTY then is
frozen. Auto-login works fine if I disable elogind, but elogind is
unfortunately a crucial part of the Guix system since a lot of things
does not work without it.

Below is attached a minimal example, simply commenting out the elogind
service in this example makes it works as expected. Running it as is
will result in the error I mentioned.

                              (auto-login "lars"))))))
