So, if I'm using a kernel I got from the 7-RC (the -latest) "repo",
how could it have gotten out of sync?

Looking at "yum list available" to see what kernel is on the "repo",
I see it's 3.10.0-123 which is the same as what's installed.

Seems like a "catch-22" wherein if you have only one kernel on the
box, you can't replace it because it's the only kernel on the box.
or something of that ilk.
