Question:
How to pause console output on system boot? The text runs too fast, I don't have time to read it, and Ctrl + S can't slow down in the right place. I need to read what luks writes at system startup, it does not get into dmesg .
Answer:
Run the command less -r /var/log/boot.log – you will most likely find the information you need. During the boot process itself – try pressing "Pause" – to be honest, I'm not at all sure what will help, but before loading grub, at the stage of BIOS boot management, this key works. Maybe it will work when the OS boots.
