I'd just like updatedb to amortize its work better. If we had some way
to track all filesystem events, updatedb could keep a live and
accurate index on the filesystem. And this isn't just updatedb that
wants that, beagle and tracker et al also want to know filesystem
events so that they can index the documents themselves as well as the
metadata. And if they do it live, that spreads the cost out, including
the VM pressure.

That would be nice.  It'd be great if there was a per-filesystem inotify
mode.  I can't help but think it'd be more efficient than recursing
every directory and adding a watch.

Or maybe a netlink thing that could buffer events since filesystem mount
until a daemon could get around to starting, so none were lost.

See "Filesystem Event Reporter" by Yi Yang, that does pretty much
exactly that. http://lkml.org/lkml/2006/9/30/98 . Author had things to
update, never resubmitted it as far as I can tell.
