@mkopec @filipleple can it break anything for laptops case?

Comment:

• USB keyboard - expected, not connected - I still think it's not the best case as it requires to manually connect physical keyboard to the platform each time we want to run the test
• WiFi - need checking, do we even have a card there?
• STB002.001 - caused by the incorrect printk settings in the OS, some details here: https://github.com/Dasharo/open-source-firmware-validation/pull/449/files; will rerun again

After setting:

cat /etc/sysctl.d/10-console-messages.conf 

# the following stops low-level messages on console
kernel.printk = 0 4 1 7

STB002.001 passed as well

This will make

        Login To Linux
        Switch To Root User

execute twice in a row on laptops, but I would guess doing this over SSH will be properly handled and won't cause any problems

Can you elaborate @filipleple ? Can you please explain where does the second one come from?

@macpijan sorry, I must've been looking at some older revision, I checked the Boot System... keyword again and it should align nicely with the changes to lib/flash, causing no trouble with laptops.
