linux default iconfrfs Publisher's description

frfs implements a fully functional in-RAM filesystem using the FUSE framework.

frfs implements a fully functional in-RAM filesystem using the FUSE framework.


With Linux, creating RAM-backed file system is easy: su to root, mount a tmpfs some place, come back to plain user.

Ah, but you’ve got to become root! I abhor being root when that can be avoided.

The solution is to use the FUSE library and pseudo- file system and let the user mount the file system.

In its current state, frfs does work quite nicely. It supports most of the usefull features of a Linux file system:

· files and directories
· symlinks
· hard links
· unlink open files, free on last close()
· most file operations:


But it lacks some functionality: some interesting operations are not yet implemented (but should be easy):

· statfs(2)
· flush(2)
· extended attributes

Also it is not thread-safe yet. Some infrastructure is there, but code is missing.




./frfs /some/place/frfs


cd /some/place/frfs
tar xjf /my/files/linux-
cd linux-
make defconfig


fusermount -u /some/place/frfs
