I'd be happy to write some stuff up.  It wouldn't
be exhaustive, but I could document what I've found out about
(the LIBC_FEATURE stuff, and some of the dependencies I've found,

the poky default and poky-tiny packages and features).

Where would you like it?  Is there a wiki page or a doc already started?
