I didn't say anything.. that's from Redhat

That's very nice for you.. Many of us having been building "custom" (aka, 
building..) kernels for our selves for many years as well.

Nobody is saying you need initrd for LABELS..  you need it for LABELS on your 
boot partition. The logic is VERY simple to understand.
