Yeah, it's not that I disagree with that; it's just the way some things
work in the distro are not really optimized for custom distros just yet.

Note that this is not something specific to livecd-tools; you want these
features to apply to normal spins and other installation methods as
well. I believe both Bill and Mark did a lot of thinking on this topic
and Bill even went as far as to propose it for Fedora 7


but that feature didn't make it in. Definitely worth thinking more
