So I'd say what you (we) need is a generic Linux kernel framework that would allow treating any regular file pretty much like a disk. Not some filesystem-specific block device emulation kludge. Btw some years ago there was a patchset adding proper automatic partition support to 'loop'; but it seems like that went nowhere, and I have no idea why something this useful did not end up being added into the mainline kernel. -- With respect, Roman
