Lower the kernel log level to 4 to suppress notice, info, and debug
messages on the console.
This prevents audit and driver messages from cluttering the screen
while keeping critical errors and systemd service status output
visible, resulting in a cleaner installer UI.

Why? There was a v2 on the list already. Hiding warnings is not a good
idea.

Hi Florian,
As per your previous suggestion, the warning messages are no longer hidden.
This has already been addressed by changing the log level from loglevel=3 to
loglevel=4 in v2 of the patch. With loglevel=4, warning messages are
displayed,
and only info and debug messages are skipped.
Thanks,
Badrikesh

Hello Florian,
You are commenting it in v2 thread already.
Correct version was merged.
Badrikesh didn't add new version tag, so it creates some confusion.

Ignore that. v2 was merged but was never tagged as v2. This is where the
confusion starts.
