Noisy GEOM_LABEL on boot of 7-STABLE

[Luke Dean]

I just upgraded my old laptop from an older 7.1 release to the
latest 7-STABLE for i386, and I started getting a lot of new
GEOM_LABEL noise during the boot process.
It says it's removing and adding labels every time it does the
filesystem checks.
What's that all about?
Should I be concerned?

This is just an old laptop with a simple out-of-the-box UFS
filesystem with no frills or geom features that aren't default.
I have never run tunefs or used glabel.
