After cvsup, I 'make world'. Read the top of /usr/src/Makefile for a
description of what this does.

AFTER 'make world', you should rebuild the kernel and install it.
This includes config, make depend, make, and, make install.
Sometimes, if you make a mistake in creating a kernel, it will not run
on your machine. For example, you may be able to build an un-runnable
kernel by including conflicting drivers, etc. However, when you
install a new kernel, the previous kernel is renamed kernel.old. So,
if a new kernel will not run, just enter kernel.old at the boot prompt
and you will get the previous one.
Note: Every 'make install' in ../../compile/<kernel name> will rename
kernel to kernel.old. So, if you build two un-runnable kernels
in a row, you will not be able to boot kernel.old. But, you may
be able to boot kernel.GENERIC, which was installed by the system.
Do 'ls -l /' and note what is there.
I have several kernels on my system:
kernel* - the current running kernel
kernel.GENERIC* - a GENERIC kernel that was installed with the system.
kernel.config* - a configurable kernel
kernel.old* - a runnable kernel just before kernel
kernel.prev* - I kept this one for some reason.
kernel.safe* - a 'safe' SMP kernel. One that I ran for a long time.
Most likely, you will have only 3. kernel, kernel.old, and,
kernel.GENERIC. I make kernel.safe by copying a good kernel to that
name, when I was playing with the kernel code.
