I have been looking for a better explanation of the options for mkudffs.
The man page is a bit sparse.

In particular, I'm looking for a way to set the volume name of them image so that after I burn the image to disk (BD in this case) when I mount it, I get the volume name rather than just LinuxUDF.

       --lvid= logical-volume-ident
              Specify the logical volume identifier.

       --vid= volume-ident
              Specify the volume identifier.

       --vsid= volume-set-ident
              Specify the volume set identifier.

       --fsid= file-set-ident
              Specify the file set identifier.
