`tmpfs` is a file system server for temporary data storage without using a real
(permanent) [[backing_store]].
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.
