If you have the resources, keep a test system and a live system.
Upgrade your live system only after you've got the test system happy, and
upgrade less frequently. It's more work, but less disruptive.

Could have changed the drivers and kept the device names, you know...
But they didn't, and it caused a lot of people pain.

Yes and no. The kernel root= parameter does require a device name and
not a label if you're using a vanilla kernel. RedHat and Fedora have
been patched to support root=LABEL=foo, but not the mainline kernel

Well, it's one louder, isn't it? It's not ten. You see, most blokes are
gonna be playing at ten, you're on ten here, all the way up, all the way up,
all the way up, you're on ten on your guitar, where can you go from there?
Where? Nowhere, exactly. What we do is, if we need that extra push over the
cliff, you know what we do? Eleven. Exactly. One louder.
