I compiled a kernel in the past a long time ago, back in college when
I learned Slackware from a friend who showed me how to install it
using floppies. I am currently (slowly) going through Linux from
Scratch. I am at the point where I need to chroot and build my system
along with the kernel in Ernest. So that will give me the opportunity
to look at building the kernel more closely.

I guess I could try to build a new kernel for my current Kubuntu
install, since I've already backed up the image there is no fear of
messing things up.

When you say initrd's / unitrs are you speaking about the
start-up/shut-down scripts that need to be run? Not sure I follow, I
am still a quasi-newbie =)
