Things to do
Changes I'd like to make:
* Fix task generation; remove the generated task lists from the module altogether and make the build generate them each time. I know Joey's been wanting this for a while, and it's sensible
* Allow (limited) builds without a local mirror. Netinst and business card images should be possible that way - they don't need a full set of packages to be present.
* Move over to deb-imgs-gen once Etch is released
