I can follow the instructions (format a cache device, mount it type bcache) and it works. What I'd like to do, however, is to have an SSD cache device, and a rotating-disk backing device, as a bcachefs filesystem. Is this something that bcachefs can do at present? If so, what's the basic procedure? Thanks, -Martin
