So if I have a box set to runlevel 3 without any kernel parameters,
what's on the monitor? Nothing?
How do I tell a tech to get to grub.conf and change the kernel
parameter? ( I can imagine this phone call!)
Or does the tech reboot ( hard, ctl-alt-del? ) and edit from the grub
screen?
Or does the kernel framebuffer display on the monitor? If so, that's
fine. I don't care about fonts or pretty colors. A simple command line
is OK.
