<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...
