It'll be rewritten by me eventually, if you don't get to it sooner, anyway.
The idea's definitely good.

One reason is it generalises to handling floppy images well: debootstrap
is currently non-interactive, and swapping floppy disks obviously
needs to be interactive. Using a "null:" interface, and just coping
with previously unpacked stuff means this can be implemented just with
changes to dbootstrap.

It also copes better with the planned future enhancement of "non static"
base systems. That is, you say "install a base system, plus ppp and pppoe"
or "install a base system, plus build-essential" and debootstrap'll be
careful to do whatever dependency resolution and such it can and do the
install. Having a single "null:" url makes it straightforward to know when
it's worth trying to download extra packages like this, and when it's not.

If you're really really desperate to avoid changing dbootstrap, that
can be as simple as adding:

	if [ "$DBOOTSTRAP_TARBALL_HACK" != "" ]; then
		mkdir -p $TARGET/
		(cd $TARGET/ && tar xzvf $DBOOTSTRAP_TARBALL_HACK)
	fi

somewhere appropriate in /usr/sbin/debootstrap.

Cheers,
aj
