I'm getting "recovering journal" when rebooting after pulling and reconfiguring my system

[Oleander via]

System boots just fine even if I get the "recovering journal" message. The 
smartctl test on my device passes.

I don't get the message if the previous session guix pull or guix system 
reconfigure are not run.

I shutdown/reboot my system with loginctl poweroff/reboot. With sudo 
shutdown/reboot I get the same behavior.

Any hint?

Thank you!
