You can simply rename it as "debian-upstream" or something. The other
way is to push the debian folder in a separate packaging branch.

I by the way saw a lot of differences between the Debian packaging and
the upstream one, which is a major issue, and the main reason why having
a debian folder upstream is a bad idea: there's 2 source of "truth", and
that should be avoided.

Which is why I wrote a debian/README.source explaining the facts. Is
that enough for you? Alternatively, I could use "debian1", but I don't
think a lot of people will even notice, and even less, understand the

I can incorporate this patch, no pb.

Right, we shall not care.

Sparc64 isn't an official port either. See here:

I don't think we should care.

In such a case, I'd strongly suggest removing this unit test until
further investigation. Is that ok for you too?

Well, in such a case, I'd suggest upstream to release more bugfix
releases then! :)

My pleasure. I hope the other changes I made are ok with you. Did you
read the debian/changelog? I removed lots of binary packages that were
not technically needed, because that's best practice in Debian (ie: the
FTP masters recommend this). All of them have a Provides: equivalent.
This also simplifies packaging a lot (ie: all /usr/bin things and
manpages are going into openvswitch-common, etc.).

BTW, I always wanted to know: is there a way to do VXLan with OpenStack
and the OpenVSwitch plugin?
