Re: [RFC 0/2] Remove Packages during Postprocessing

[Henning Schild <henning.schild@siemens.com>]

Hi,

my opinion on that is clear. Fix it upstream or live with those
packages. You are either on a distro or fiddle around and tune
everything until you are the only one on the planet testing your setup.
That is Isar vs. yocto ... whoever thinks they _need_ that should maybe
think again. If they need it they can put it into their own layer or
use yocto ;).
I do not think upstream should carry such hacky features unless we get
better reasoning ... Removing "required" packages has the potential to
break your image in funny ways ... that is much more expensive than a
few MB disc space. All affected packages are likely already cleared and
vulnerabilty monitored by someone else, find that someone and share the
cost!
