UDF and CD-RW

[Laszlo Nagy]

  Hi All!

I'm trying to use packet writing software on FreeBSD. The FreeBSD 
counterpart of the Linux "udftools" package is the "udfclient" port. 
However, I cannot use it. It does not allow me to create a new 
filesystem, telling me that I need to packet-format first. But I don't 
know how to do that. Can you please help?
