Many of these items are resolved in the mhatle/rpm5 branch that is part of
poky-contrib.  I'm trying to get the work finished for inclusion in the next day
or so.

But for a minimal image, RPM likely is too big of a hammer for the filesystem
design you want and IPK is likely more useful to you.

The place where I see RPM being needed is in medium size to larger (CGL) style
systems.  Also places where a sat solver is necessary for field upgrades... even
though thats not quite working yet.
