I use bind mounts as well. I have several external arrays connected over
e-sata (I like the enclosures) and I use it for more than MythTV, but bind
mounts just make it easier to add a single mount that the entire system
just recognizes afterward. I toyed with union mounts, but it decreased the
throughput speed by more than I was willing to accept.
