bug#27580: Elogin doesn't start properly

[William]

On my GuixSD VM (Guix release 0.13) elogind doesn't start at startup,
despite (elogind-service) being used in config.scm. I am not using
Xorg or a desktop manager like Slim.

Elogind only starts when loginctl is executed as loginctl activates
elogind via DBus, meaning that it doesn't record any logins before
loginctl is run. I don't believe that this is intended; my Arch Linux
install doesn't miss any logins.

My config.scm:

--8<---------------cut here---------------start------------->8---
(services (cons* ;; Networking
                   (service wpa-supplicant-service-type)
                   (service connman-service-type (connman-configuration))
                   (service tlp-service-type)
                   (service thermald-service-type)
                   (udisks-service)
                   (polkit-service)
                   (elogind-service)
                   (dbus-service)

                   %base-services))
--8<---------------cut here---------------end--------------->8---

Output (just started up vm):
