Does it matter which partition "home" is? I was going to use sda9 in the arrangement I proposed. New hard-drive just arrived and I will be giving this a go tomorrow... I've quite the mound of reading to get through beforehand (at least Ubuntu offers a clear, easy to follow install guide which I can view on my life saving Nokia N900 as I work on the box ).
I'm swapping the Ubuntu and Fedora locations (Ubuntu sda1&2, Fedora sda3&4). Ubuntu was the choosiest of choices in this thread so I'll use it first (so long as it provides me fdisk, mkfs and fsck on install otherwise I'll have to Debian first which I know includes them).
