       -o kernel
              Behave more like the kernel ext4 driver in the following
              ways: Allows processes owned by other users to access the
              filesystem.  Uses the kernel's permissions checking logic
              instead of fuse2fs's.  Enables setuid and device files.
              Note that these options can still be overridden (e.g.
              nosuid ) later.

       -o direct
              Use O_DIRECT to access the block device.

       -o cache_size
              Set the disk cache size to this quantity.  The quantity may
              contain the suffixes k, m, or g.  By default, the size is
              32MB.  The size may not be larger than 2GB.

   FUSE options:
       -d -o debug
              enable debug output (implies -f)

       -f     foreground operation

       -s     disable multi-threaded operation
