That's the kind of dump-ish flexibility I want to be able to use with CDs
and DVDs.  sysutils/cdbkup is somewhat vaguely similar to dump in how it's
invoked.  I like the way the resulting CDs are iso9660 with a tarball
containing the data thereby allowing me to manually fiddle with the data.
Would this modification to dump(8) also do this or would the CDs be
written raw?
