This question just rolled in a few hours ago. I'm unfamiliar with BackTrack but it appears to be a highly modified Ubuntu installation which from the site's appearance - dropped most ties to Ubuntu. I know we've discussed "What distros we should allow" and seem to have agreed on the entire Ubuntu Family (Kubuntu, Edbuntu, Mythbuntu, Ubuntu Studio, etc) Those which stay close to the project.
How should Distros like BackTrack be handled?
