WIP: run archiso in make test
WIP: The console is a mess, with the GRUB TUI... I wonder if
run_archiso.sh should perhaps have some sort of
-q quiet option, which logs to a file? But that wouldn't be very handy for later (#2 (closed)) running this on CI and seeing output.
Or, I think better, another option to avoiding showing the console all together, and just stream the serial console output. That may actually be more suitable for this here.
The 30s wait on GRUB TUI is also a minor PITA.
