He wants to KISS. So lets make it even simpler.
- master: patched source
- upstream: upstream source
Convert to 3.0 (quilt) format and keep it out of git:
echo "3.0 (quilt)" >debian/source/format
echo "debian/patches" >>.gitignore
echo ".pc" >>.gitignore
And then to build you use (or pass it to git-buildpackage):
debuild --single-debian-patch
There is no need to manually create any patch with git format-patch.
dpkg-source will create a fresh debian/patches/debian-changes on every
build containing all your differences between upstream (well, the
orig.tar.ext) and master outside the debian dir.
The advantage of this over the 1.0 format is that it supports
orig.tar.bz2, has the debian dir as tar (so it can contain binary data
too) and changes to upstream in debian/patches/debian-changes that can
easily be extracted by upstream or for a patch tracker without having to
know your git.
