MTFS is a stackable file system which uses lower file system's directories as its branches, and automatically generate multiple identical replica of files or directories, while everything being kept transparent to users.

This looks interesting - pretty similar to GlusterFS I guess?

Short of reading the code, is there any description of how this works?
Is it a user-space FUSE driver, a kernel module, something else?
How does it achieve increased reliability?  How does it deal with faults?

Cheers, Andreas
