I noticed that my headless server running GuixSD was busy when I am not
doing anything. When I looked at top I saw mingetty consuming 40% CPU
...

If I plug in a console display, I see the login prompt is being rapidly
printed over and over. If I hit the console return key the printing
stops and mingetty stops using CPU.
I am running a relatively recent GuixSD built from git checkout ...
