Ubuntu PXE

cd /etc/initramfs-tools/
vim initramfs.conf
Edit BOOT=local to read BOOT=nfs

Before we update the init images, we should back up the current ones just so we can still get back into the local install if ever anything goes horribly wrong…

cd /boot
mv initrd.img-2.6.20-16-generic initrd.img-2.6.20-16-generic-OLD

Now we want to update the initramfs image:

update-initramfs -k all -c
