  #for_device
  #reset

  #reset is called by StorageManager during probing
  Stores the information into the singleton object
  Reads the information in the first call to #for_device

  #fs_attribute(attr)

  #fs_attribute calls #read_fs_attributes unless userdata_value(:fs_attributes_already_read)
  #read_fs_attributes instantiates a FilesystemReader and stores all its results in userdata

  userdata_value(:crypttab_name) -> Used for importing mount points (at least)
  userdata_value(:encryption_process) -> An object of type EncryptionProcess
                                         that is updated through the process
