How can Tracker (reliably) detect if a resource is on an external drive?
I can't believe that this works for anything but the trivial case where
/dev/sdX is directly mounted. But if the disk is e.g. LUKS encrypted,
then there's already a device mapper in between. It get's even worse
with all the possibilities that FUSE and bind mounts offer.
