does it have to be fuse? cant you mount a disk image with loopback

[andrewflnr]

Wouldn't a disk image have a fixed size? It could be a pain to resize.

But not trivially loop-mountable. I guess it's possible, though. https://unix.stackexchange.com/questions/268460/how-to-mount...

[metadat]

But will the disk image be fully stored in memory? No.. not with loopback. Either that, or it won't be mutable in memory with commit on unmount.

[generalizations]

Put the disk image inside a ramdisk and it's in memory. Write a script for saving to physical disk when dismounting, and you're done.
