Hi Ludo'
thank you for looking into this issue!

OK, so this is deterministic now :-)

actually they do fail but they are not respawned, the services that get
respawned are term-tty[1..6]

I have to use "sudo" to be able to start and "guix container exec" a
shell in it (I mean: sudo guix container exec...)
I used that command in another terminal so I could see the console
messages from the container

oh yes! I did not realized that my container was there waiting for me
:-)
...I also did not realized thet the container is started as a foreground
process, so we nees to background
I used pstree too, we need a better way to interact with a container (by
name and not by PID); sorry but I still cannot help here, my Guile
proficency is still too low; anyway this is tangent to this bug

yes, I see: I stopped term-tty[1..6] and the failure messages disappeared

as pointed above the faining services are term-tty[1..6],
console-font-tty[1..6] fails but do not get respawned do they are not
the real issue

I'll try to remove term-tty[1..6] manually from services declaration, if
I manage to "manually" solve this I'll report here
> Thoughts?
since mingetty does not make sense in a container I'd remove
term-tty[1..6] (and console-font-tty[1..6]) automatically and by default
when we create a container via "guix system container..."
Thanks!
