config FUSE_FS tristate "FUSE (Filesystem in Userspace) support" select FS_POSIX_ACL help With FUSE it is possible to implement a fully functional filesystem in a userspace program. There's also a companion library: libfuse2. This library is available from the FUSE homepage: <http://fuse.sourceforge.net/> although chances are your distribution already has that library installed if you've installed the "fuse" package itself. See <file:Documentation/filesystems/fuse.txt> for more information. See <file:Documentation/Changes> for needed library/utility version.
