+Yeah in this case if the conversion is done, I'd just recommend
+installing filesystem --nodeps and the rest should flow. It's not ideal
+certainly, but there is still time to polish this a bit before upgraders
+get hit by this (and as there will be updated rpm packages in the stable
+releases, it should mitigate this specific problem, but we should still
+see if we can do things better)
