Hi,

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) ?

Thanks again,

db

    Well, first it depends on how the bootable CD thing works..
    does it require a ISO9660 filesystem? If so, your best bet
    would be to get iso9660 bridging working (basically,
    sticking a iso9660 level 3 filesystem at the back of a UDF
    filesystem that has its contents pointed to the contents on
    the UDF filesystem - how hybrid UDF/ISO9660 DVD discs work).
    Then presumably the bootableness would just be added on to
    that.. If you can do it without needing ISO9660, you could
    prolly just write a program to search the disc for the file
    to load, then update the boot info to boot from that file.

    Do you know if the bootable cd spec is publically avaliable
    (and where) ?
