Agreed. My initial start of work in this area looked exactly like this:
a single package. See
https://github.com/tpetazzoni/buildroot/commit/58413ab16c6b203dca48db182e74e59ae73c958a.
Note: this commit is far from being something that works. If I had
something that worked, I would have submitted it.

See commit above :-)

Pretty much what I did, yes :-)

Thanks,
