+This will have a impact on the usability of the $ARCH keyword in url for
+urpmi. Ie, the name must be derived from what we use for name of arch in
+rpm, given the way this feature was coded.

+Which in turn is arbitrary, iirc, but we may need to keep compatibility
+with previous mandriva version, as we plan to offer a upgrade path.
