Subject: [PATCH 1/2] meta: recipes-support shrink with preconfig instead of postproc
Date: Tue, 23 Jul 2019 13:42:23 +0200 [thread overview]
Message-ID: <20190723114224.22776-1-henning.schild@siemens.com> (raw)
From: Henning Schild <henning.schild@siemens.com>
This adds two support packages to shrink an image and keep it small in
case apt/dpkg will be used on the system later on.
An alternative would be postprocess functions, they would be run-once
and if the system continues to receive package updates new files will
not be cleaned up.
