Hey Danny,

Sorry for the delay in response. I saw no behavior change until I added the
(mount? #f) line. This fixed a number of services, but d-bus fails to
start. I encounter further issues including X Server failing to start and
the inability to log in (when I type in a valid username it immediately
fails 3 times and prints the standard message... I don't have password
hashes in my config, but IIRC last time I installed guix I was able to log
in without setting a password either imperatively or declaratively). Due to
the latter issue I was unable to test the program you posted, but it sounds
like Ludovic was able to describe what would happen if I had been able to?
I assume the non-d-bus errors are related to the lack of d-bus.

I uploaded a new video of my startup at
https://drive.google.com/file/d/1bVdiCM1BKAmY-1y1XydI4ol7BCCkQ2Xk/view?usp=drivesdk
It's ~50s long, but seconds 20-45 are the system retrying d-bus a number of
times.
