   7 UFS OPTIONS
   8 ===========

  10 ufstype=type_of_ufs
  11         UFS is a file system widely used in different operating systems.
  12         The problem are differences among implementations. Features of
  13         some implementations are undocumented, so its hard to recognize
  14         type of ufs automatically. That's why user must specify type of
  15         ufs manually by mount option ufstype. Possible values are:
  16
  17         old     old format of ufs
  18                 default value, supported as read-only
