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:
<https://github.com/libfuse/>
although chances are your distribution already has that library
installed if you've installed the "fuse" package itself.
See <file:Documentation/filesystems/fuse.rst> for more information.
See <file:Documentation/Changes> for needed library/utility version.
If you want to develop a userspace FS, or if you want to use
a filesystem based on FUSE, answer Y or M.
