Hi Danny & Leo,

Thanks for the quick response!

Not clear what you wanted so I didn't try this.

I did that, see below ...

I removed agetty-service but agetty didn't run, see below ...

I did git-pull & make to get guix (GNU Guix) 0.14.0.1879-06a9 and 'guix
system reconfigure' >>> the console is still blank.  (my G36)

Then I removed agetty-service, reconfigured and rebooted >>> the console
is still blank. (my G37, sys.scm attached)

FWIW, I don't see agetty running ...
