[RFC PATCH 0/3] Reproducible build

[claudius.heine.ext@siemens.com]

From: Claudius Heine <ch@denx.de>

Hi,

this patchset contains a implementation of my proposed solution for
reproducible builds.

I am currenlty not quite sure if that is the right approach, but it is
the simplest I can think of currently.

As already described in my proposal, this patchset does the following:

  1. Takes care that the package cache in the isar-bootstrap root file
     system contains all the packages used for this distro/architecture.
  2. A tarball is created after the package cache contains all the
     packages needed by the image.
  3. This tarball can be used as the basis of subsequent builds by
     setting a bitbake variable.

This is just a first draft of this feature, maybe we can further improve
some steps and maybe there are better ideas to improve the usability.

Cheers,
Claudius
