This doesn't work for my environment:

The requirement is that every debian source tree has a ./debian/rules
file (w/ the standard rules like binary, clean, ...). This is called by
upper level build machinery (git-buildpackage, dpkg-buildpackage, ...)

The idea behind is building all packages exactly the same way - one
standard workflow, that just takes a source tree (from git) and spits
out some .deb files.

It shouldn't (at least I dont intend to). Haven't tried where exactly
the generated debian/rules file lands in your case.

I don't think so. In essence I just replace the generated rules file by
a fixed one. Okay, it will take *a little* bit longer, as the rules file
now calls `make kernelarch`, `make kernelrelease` and `make
kernellocalversion`, before starting actual build. But that shouldn't be
the big deal, IMHO.

I try to bring these two world a bit closer together.

I intend not to.

Actually, the official Debian way for Kernel build is entirely
different, and that's really complicated and hard to really understand
(that's why I'm doing this here).

But here I'm just coping w/ the first entry point into the build
process, which now becomes `./debian/rules binary` instead of
`make bindeb-pkg`. The final result (in the .deb files) should be
the time (unless I did something wrong).
