The one reservation about this direction is that there are a few devices where I'm not sure how to attach the metadata (keyring, conf, and other random bits in the osd_data dir) to the device: the SPDK NVMe driver, and kinetic. These are somewhat obscure, but I'm curious if there are other ideas floating around about how this should be approached... sage
