+
+UFS OPTIONS
+===========
+
+ufstype=type_of_ufs
+       UFS is a file system widely used in different operating systems.
+       The problem are differences among implementations. Features of
+       some implementations are undocumented, so its hard to recognize
+       type of ufs automatically. That's why user must specify type of 
+       ufs manually by mount option ufstype. Possible values are:
+
+       old     old format of ufs
+               default value, supported as read-only
+
+       44bsd   used in FreeBSD, NetBSD, OpenBSD
+               supported as read-write
+
+       ufs2    used in FreeBSD 5.x
+               supported as read-write
