Unfortunately bitbake/oe lack good descriptions of the two. But those
can be found here:
https://devmanual.gentoo.org/ebuild-writing/variables/ and probably
also in FreeBSD

That means that debianization should be done on S, not D.

And OE also has 'D = "${WORKDIR}/image"', which seems to be missing in
Isar.
