[Piuparts-devel] Bug#458929: piuparts: can't test apt/debfoster and their dependancies

[Lucas Nussbaum]

Package: piuparts
Version: 0.28

Hi,

If I run piuparts with --warn-on-others on zlib1g, it will fail in that
way:

0m14.2s DEBUG: Starting command: ['chroot', '/tmp/tmp5tYw8U', 'apt-get', '-y', 'install', 'zlib1g', 'zlib1g-']
0m15.2s DUMP:

Since we can't do anything about that, it would be great to:
- either detect that the package is already installed, and continue running without trying to "apt-get install package package-".
- or simply detect that case and exit gracefully.
