many thanks for pkt writing driver.
One question however.
I'd like to build a UDF-bootable CDRW (or CD-R, the
most important word here is bootable).
That needs an Eltorito boot loader and a catalog build
from the list of files and directories on the CD.
mkisofs does it on the fly for ISO9660 CDR (or CDRW).
Have you an idea of how I could do that (with an
extension to mkudf) ?
