-Write support requires a block driver which supports writing.  Currently
-dvd+rw drives and media support true random sector writes, and so a udf
-filesystem on such devices can be directly mounted read/write.  CD-RW
-media however, does not support this.  Instead the media can be formatted
-for packet mode using the utility cdrwtool, then the pktcdvd driver can
-be bound to the underlying cd device to provide the required buffering
-and read-modify-write cycles to allow the filesystem random sector writes
-while providing the hardware with only full packet writes.  While not
-required for dvd+rw media, use of the pktcdvd driver often enhances
-performance due to very poor read-modify-write support supplied internally
-by drive firmware.
