[Pkg-uml-pkgs] Bug#372937: rootstrap: add support for non-debian .deb archives

[Andreas Beckmann]

Package: rootstrap
Version: 0.3.22-1
Severity: wishlist
Tags: patch

Hi Mattia,

although it's possible to add e.g. a local package archive with the
[debian]sources= settings, this can't be used to install local packages
because apt doesn't trust this archive.

So rootstrap needs to configure apt in the target to trust the other
archives I want to use, too. This needs to be done before installing
additional packages from the [debian]install= list.

My local solution was the following:
- my gpg key is available in a package on the local mirror and the
  postinst script installs this key with apt-key add
- patched modules/debian:
  * install packages listed in [debian]keyrings= with --force-yes to
    override the missing trust
  * run apt-get update (to trust packages from the local archive)
  * install the packages from [debian]install= which now may contain
    local packages, too
The patch for rootstrap.conf, modules/debian is attached, but probably
needs more eyes and thoughts before it's applied.
