+
+There are two possibilities:
+
+The first is to use 'mount --bind DIR TMPDIR' to create a copy of the
+namespace under DIR.  After mounting the FUSE filesystem over DIR,
+files can still be accessed through TMDIR.  This needs root privileges.
+
+The second is to set the working directory to DIR after mounting the FUSE
+filesystem.  For example before fuse_main() do
+

+      fsfipi: A framework supporting a cascade of filters, which modify the

+      higher level (i. e. the requests, what operations this filesystem shall
+      do) and for the lower level interface (performing the file operations).
+      Only the lowest level filter uses actual system calls to store files on
+      the real file system (localfs) or there is a possibility of making sshfs-
+      like lowest level filter. The only highest level filter now is
+      fuse_interface, which implements a fuse filesystem daemon and sends the

+      Squashfs. It uses the
+      lzma
+       compression algorithm.
+      It splits each file into fixed-size blocks and compresses the blocks
+      together in larger clusters, so that blocks from different files are
+      compressed together for smaller size. Directories, inodes and block lists
+      are also compressed. In some cases, it beats Squashfs by a factor of four
+      in terms of compression power. On the flip side, it is noticeably slower
+      than its peers, and requires more RAM.

+  Description
+      usmb lets you mount SMB/CIFS shares, as per "Map Network Drive" in
+      Windows' Explorer. Unlike the other SMB FUSE filesystems, which emulate
+      Network Neighbourhood, usmb lets you mount arbitrary SMB shares,
+      including hidden ones that you can't browse.
