Note that the FreeBSD CD-ROM driver has no support for multiple tracks or ISO 9660 multi-session CDs yet at all. Well, the driver offers just the entire data area on the disk without any track boundaries, this should be sufficient for an ISO 9660 multi-session CD. However, mount_cd9660 need to be taught about CD-ROM TOCs. > Also is is possible to write the output of mkisofs directly to a cd > rather than to an intermediate file.

It prevents you from test-mounting and test-reading the image though. And, with about 10 frisbees due to starving the CD-R, you've compensated for the costs of your 600 MB disk space. :-} -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
