<gripe-mode: inaccurate subject lines>

So the issue isn't /home being btrfs (as you said in the subject), but 
rather, it's /home being an explicitly mounted subvolume, since btrfs 
uses bind-mounts internally for subvolume mounts.

Makes a difference for folks like me who have /home on a fully separate 
btrfs.  You had me wondering for a moment, tho as it happens I don't use 
updatedb either, but I was still wondering what weird bug and how it 
might otherwise affect me.  An accurate subject line would have helped...
