bug#54786: Installation tests are failing

[Mathieu Othacehe]

Hello,

The installation tests are failing this way:

--8<---------------cut here---------------start------------->8---
conversation expecting pattern ((quote pause))
Apr  7 17:41:58 localhost installer[227]: guix system: error: failed to connect 
to `/var/guix/daemon-socket/socket': Connection refused 
--8<---------------cut here---------------end--------------->8---

this is right after the 'guix-daemon' service is restarted. It looks
like this regression is introduced by the switch to the new Shepherd
release.

See:

Thanks,
