Isn't this issue resolved in "[RFC 0/7] Postinstall improvements" too?

Ah, possibly.  I haven't really been following that thread.  I'll take a
look.

I found the patch that I guess you were referring to:

http://lists.linuxtogo.org/pipermail/openembedded-core/2012-September/029913.html

Personally I don't like that solution so much; the reliance on
NATIVE_ROOT containing the appropriate bits seems a bit fragile.  But I
suppose it's a matter of opinion.
