'Twas brillig, and Olivier Thauvin at 26/07/12 08:05 did gyre and gimble:

+This is an interesting idea, but I wonder why the redhat guys didn't do
+it that way so I'll discuss it with them when I get a chance.
+
+I'm also not sure where the circular dep is (I can't see why filesystem
+has to be upgraded to install the newer rpm: but I'll have to do some
+tests next week in a VM to see if it comes to light).
