+Filesystem type
+~~~~~~~~~~~~~~~
+
+The filesystem type given to mount(2) can be one of the following:
+
+'fuse'
+
+ This is the usual way to mount a FUSE filesystem. The first
+ argument of the mount system call may contain an arbitrary string,
+ which is not interpreted by the kernel.
+
+'fuseblk'
+
+ The filesystem is block device based. The first argument of the
+ mount system call is interpreted as the name of the device.
