On a ROCK64 system-on-chip, herd start elogind fails.  This is guix
commit 87624540b486d710749ad00ef5aa427a9e5c1d0c after the
core-updates-frozen merge.  This breaks sway for me, which I start
from the Linux console.

But if I

    Revert "gnu: elogind: Update to 246.10."
    
    This reverts commit a0bf66ab9432675f86095d9a2533d7b80f58a668.

then it is working again.

(Actually on reconfigure in order to build python-dbusmock I also need
to add #:tests? #f to python-dbusmock.)

I shall try out if updating to

commit 488f1c589df00e802163af534294d93372e5c025
    services: dbus: Wait 1 minute for elogind to get ready.

helps, but the failure is immediate, so that is probably unrelated.
If it does not help, I will bisect the elogind versions.

Attached is my config.  (Note that the setup is unusual; to boot, I
copy all files referenced in /boot/extlinux/extlinux.conf from
/gnu/store to /boot/gnu/store.)
