I've spent about an hour searching without finding an answer. Is there any way from the kernel command line (i.e. by editing the GRUB entry) to control the number of lines on the console? I installed Fedora 39 on a USB stick so that I can use it to boot other computers to diagnose problems with the installed OS. The problem is that when it is booting, the latest console messages are off the bottom of the screen so that I can't see what it's doing (this is on a standard 1920x1080 HD monitor in this case). If the boot hangs, then of course the last few messages are the crucial ones to see.

Once the machine is booted, of course, then I can log in and use tools such as "stty" to set the number of rows and cure this problem, but I need something that will take effect during system startup before the login prompt comes up.

Thank you,
