I see that wormcontrol supports multi session recording. Is it possible to use mkisofs to record multiple sessions. I'd like to be able to write separate directory trees in different sessions. eg write /bin in one session and /usr/bin in another. Also is is possible to write the output of mkisofs directly to a cd rather than to an intermediate file. Use of suitable buffering should allow this. If I pipe the output of mkisofs to /dev/null it seems to write at 500+ kb/sec (which is fast enough). Writing the file generated by mkisofs back to the same disk seems to be alot slower (160Kb/sec), I assume this is just due to accessing the same disk for read and write but I am a FREE-BSD newbie and I really have no idea how much things will be slowed when writing to the CD-R using an ISA scsi card (1505). Writing directly would be very handy as it would save time and I wouldn't need to leave 600+ Mb of free disk space just for temporary disk images. The very reason I'd like to use CD-ROM backup is so that I don't have archive to hard disk (or tape). Sorry for the long posts and many questions. Tim. PS. I'm not much of a programmer but I'd be willing to help any development on this side of things.
