That's what I'm saying.

Ah, so not automated.

For this project I'm not using X, just using the kernels frame buffer.
So no VNC for me.

That attached script is similar to what I'm doing, only I plan on using
grub legacy instead of lilo. Unfortunately LFS switched to grub2, so I
have to back track. I wont be completely to spec with the latest LFS,
but for bootloaders, don't think either of us care.
A big old stinking pile of genius that no one wants
