Outside of the OE repo, no.  Outside of "conf/" yes.  And yes, this
would require some re-org, perhaps.  Or perhaps not (and we make
something like contrib/ but, I don't know, I suck at naming).  And yes,
with an updated local.conf.sample, getting the overlay stuff right is
trivial.

But yes, not generically done at all improvements would end up in the
distro overlay until someone wanted to fix it generically.

Think of it this way, it would also make it easier to show how to make a
"custom Angstrom" the right way, rather than cp
conf/distro/angstrom-2008.1.conf conf/distro/mydistro.conf which I have
gathered would be a good thing.
