You've created it, or are just thinking about it? If the former, URL?

That's not a reason for the package not to enter stable. What if someone
with some source CDs wants to modify the installer? Why shouldn't they
be able to just use your package with their updated .udebs?

That seems plausible, but won't necessary work on the buildds -- you
don't necessarily have network access, although you probably do. You
also don't generally have root.

Huh? All the sources of what? Every udeb? Including libc? That sounds
like a complete non-starter.

Which would suck. If you need root, you have to do it, though.

Alternatively, you might be able to arrange to build the images for each
arch on a single box; this would not suck. Making bootable sparc images
on an i386 box (or vice-versa) might be tricky.
