  great, just what i needed ... yet *another* strategy. in any event,
can i confirm that if i have the recipe for RPM4, i can use
PREFERRED_VERSION to use it for the OE build and, later, to install
RPM4-format rpms built elsewhere?

  also, *if* i build an image based on RPM4, is it feasible (or even
possible) to upgrade the whole thing to RPM5 later? i'm not sure i
even want to think about the grief possibly involved in that.

  thanks muchly.
