You can't use g-file-storage without a backing file or a backing device. The information presented by g-file-storage to the host always appears as /dev/sda (or sdb, ...). The partitioning into sda1, sda2, ... is done by the host, not by g-file-storage. > Also, how to use that device. Which functions to call (read, write, ioctl > ...) ? Those system calls will all work with g-file-storage.
