The inheritance chain is interruptable. It is interrupted as soon a
package has been built explicitly for the parent dist. For example,
once somebody rebuilds packages for dist-f16 because of library
upgrades, dist-f16 no longer inherits those packages from dist-f15
+updates. Now guess what happens if subsequent builds for dist-f16
fail.
