hide all boot process in Buster

[aristosv]

I am working on a raspberry pi running Raspbian Buster lite, and I want to remove all boot information. Basically I want a black screen, no text or prompts or anything. This is what I have so far.

Code: Select all

echo hide rainbow
sudo sed -i '1 i\disable_splash=1' /boot/config.txt

echo hide boot icons
sudo sed -i "1 s|$| logo.nologo quiet splash|" /boot/cmdline.txt

echo hide boot messages
sudo sed -i "1 s|$| quiet splash|" /boot/cmdline.txt

echo disable login prompt
sudo systemctl disable getty@tty1.service

echo hide blinking cursor
sudo sed -i "1 s|$| vt.global_cursor_default=0|" /boot/cmdline.txt

It's pretty close, but I still get some text during the final stages of booting.
This is all that shows up now.

Any idea what I can do to hide this also?
Thanks

Remove the 'console=tty1' and replace it with 'console=serial0' ?

[aristosv]

yes, this worked, thank you.
If I understand it correctly, this redirects the console to serial?

Yes. You could use /dev/null if that's not good enough for you, but I'd always advise logging something *somewhere*.
