    Yes.

    Joey would be the authority on this, but it should be the case. If
    debootstrap is calling wget in its default configuration, there are a
    minimum of 20 retry attempts on a given download.

    FWIW: I'm the original author of the chroot install instructions, and I
    typically install systems over a dialup connection (56k nominal). It's
    quite doable.

    The situation improves markedly, however, if you have some sort of
    cache. You can run a standard Web caching proxy (e.g.: Squid) which
    will do this pretty much transparently, or use the apt-proxy cache
    program, specifically designed for the purpose. Running apt-proxy on
    a system on your local network _vastly_ improves update performance for
    multiple hosts as any given package need be fetched only once.

    My experience is that a relatively rich proxy cache needs about 2-4 GiB
    storage (~2000 packages).

    Sure. Your packages are stored in /var/cache/apt/archives. You can
    fetch the list of packages and download them to any medium, then copy
    them to this location, to avoid download times.

    The entire Debian package management system is somewhat involved, and a
    lot of the knowledge of it is sort of just plain institutional, though
    there are extensive docs at the Debian project website, particularly
    Developer and Policy docs:

        http://www.debian.org/
        http://www.debian.org/doc/devel-manuals#policy
        http://www.debian.org/doc/user-manuals#apt-howto
        http://www.debian.org/doc/user-manuals#quick-reference
        http://www.debian.org/doc/devel-manuals#dpkgint

    Also, Osamu Aoki's _Debian Quick Reference_ is a very useful guide
    following more a "cookbook" how-to model, and focussing strongly on
    package management tools:

    The GMANE Usenet gateway:

    Point your newsreader at it.
