It is based on [[libdiskfs]]. Even though there are other possibilities of creating a [[libstore/examples/ramdisk]] and running a regular, for example, [[`ext2` file system|ext2fs]] on it, having a real `tmpfs` is better, as it need not deal with the additional block-level indirection layer that `ext2` (or any other disk-based file system) imposes. `tmpfs` generally works, although it requires root permissions for file content; see the [[discussion]] sub-pages for the past and current issues. There is a [[!FF_project 271]][[!tag bounty]] on this task.
