Debootstrap Ubuntu from Gentoo

From NAS-Central Buffalo - The Linkstation Wiki

Why?

The original way of installing Ubuntu is to use a temporary installation of Debian. This small guide is for people who already have a running system, such as Gentoo.

How?

First, prepare your target partition with 'fdisk' and 'mkfs.ext3'. I'll assume your target partition is mounted at /mnt/ubuntu/

Now emerge debootstrap:

$ sudo emerge -av debootstrap

By default, debootstrap only has package information for Debian, not for Ubuntu. We'll need to get the Ubuntu equivalent:

$ sudo su -
# cd /usr/lib/debootstrap/scripts/
# wget http://food.fishcracker.net/~stock/debootstrap-feisty.tar.gz
# tar -xzvf debootstrap-feisty.tar.gz

Now start the debootstrap:

# debootstrap --arch powerpc feisty /mnt/ubuntu http://archive.ubuntu.com/ubuntu/

Then continue according to the Ubuntu using temporary Debian guide.
