| I solved this by calling APT twice, once to download the package with
| root on /, and once to installing with root on /target.  This works.
| The code look like this (from rootskel - apt-install):
| 
|   PATH=$PATH:/target/usr/bin:/target/bin:/target/usr/sbin:/target/sbin \
|   LD_LIBRARY_PATH=/usr/lib:/lib:/target/usr/lib:/target/lib \
|   /target/usr/bin/apt-get \
|       -o Dir::State=/target/var/lib/apt \
|       -o Dir::State::status=/target/var/lib/dpkg/status \
|       -o Dir::Cache=/target/var/cache/apt \
|       -o Dir::Etc=/target/etc/apt \
|       -o Dir::Bin::methods=/target/usr/lib/apt/methods \
|       -o Dir::Bin::gzip=/target/bin/gzip \
|       -o Dir::Bin::dpkg=/target/usr/bin/dpkg \
|       -o Dpkg::Options::=--root=/target \
|       -y --download-only install $*

This breaks when libc breaks backwards compat, doesn't it?  Undefined
symbols and such? (And as a minor point, we want "$@" not $*).  And it
requires sources.list set up.

| I would rather have something that handles dependencies.

So would I.  But I'd like to have it in debootstrap. :)
