if you have a clever (cheap) idea how to do it, i'm all ears.
the problem is, that the package cache must be available in the chroot.
so, symlinking a directory outside of chroot wouldn't work.
bind-mounting also sucks, because it raises the requirements to having a
2.6 kernel running[0].
oh.. but we could hardlink them.. the hardlink and integrity problem we
have with the whole chroot doesn't hold for .deb files, as they are
versioned (so no accidental overwriting and changing contents outside of
chroot from within.. unless the file was only partially fetched, but
then that is actually the desired behaviour anyway).
so, indeed.. one could hardlink these these.. will have a look at it at
thursday (but feel free to send a patch if you've time to kill before
thursday).
[0] once we get ro-bind mounts, i'll reconsider bind-mounts.
