Yes, sure, we do it the same way. But once you have it in your patch
stack, the packet works. Everything else is extra effort, without
anybody really being interested in it.

You cannot enforce naming policies; we use the normal packet name for
that, which is usually what you get if you extract a packet. There are
activities on the way to restructure our packets to have something like
As I said before: I see no point in talking all similar projects out
there into using the same format. If you want to push something, make
yet another patch repository, plus automated scripts which make it easy
for the maintainers of the projects to automatically convert and push
their patches in.
Regarding the patch format, we have our own header ontop of it, to
specify things like the upstream status, source or the error etc. In the
future it will most probably be the canonical patch format used for

The community tool for getting patches in order is quilt; so we use
quilt like series files in our patch repositories. It also makes
patch development easy: just link the patch dir into a breaking project
and use quilt to maintain the patch.

We agree that libtool has problems. But it is the same with libtool as
with for example cmake: People come and want to do everything better
what has been done by skilled developers for years. They make something
new, and in the end it does the deficiencies 100% perfectly, but on the
way 50% of the old functionality is lost. Cmake for example still cannot
cross compile as far as I know, and it breaks the known-for-decades way
of building packets with ./configure && make && make install, together
with well established methods like --with-foobar=blub and --enable-baz.
So IMHO the only solution is: fix libtool.

So for the moment I'd say that we are generally interested in such a
project, taken that it is structured in a way that we may discuss a
generic patch + documentation format and build automatisms to push
patches from the build systems into a QM project. Let's do some more
thinking about how to structure it correctly...
Rene, what is your oppinion? Would you also be interested? It might also
be a good idea to ask buildroot, open-embedded etc.
And, of course, it would have to happen under a neutral organisation. I
wouldn't also mind to let this thing be quality.pengutronix.de to get
the marketing effect ;) but if we want to be it a success, it must be
strictly vendor neutral. LTP could be a candidate, or the Linux
Foundation. Has anybody contacts?
