fnunbind composite_name
SUNWfns
fnunbind unbinds the reference of composite_name.
For example,
eg% fnunbind user/jsmith/fs/unbinds the reference to which the name user/jsmith/fs/ was bound.
Note that an fnunbind on a name of a context will fail because such a context cannot be unbound without destroying it first with the command fndestroy.
