What is actually happening here ?

I have FreeBSD on /dev/sda2.

I do these entries from Fedora 14.

      -t, --types vfstype
              The argument following the -t is used to indicate the filesystem
              type.   The  filesystem  types  which  are  currently  supported
              include: ...
              ..., ufs, ...

Mount options for ufs
       ufstype=value
              UFS  is a filesystem widely used in different operating systems.
              The problem are differences among implementations.  Features  of
              some  implementations are undocumented, so its hard to recognize
              the type of ufs automatically.  That's why the user must specify
              the type of ufs by mount option.  Possible values are:

              old    Old  format  of  ufs,  this  is  the  default, read only.
                     (Don't forget to give the -r option.)
