Hi, > http://ubuntuforums.org/showthread.php?p=4288486
You have a problem with the formatter program genisoimage, a clone of mkisofs. growisofs uses mkisofs (or a clone of it) as formatter. It obtains multi-session info from media, operates mkisofs accordingly, and directs the resulting image to media by its own DVD capabilities (which are ecxellent, btw). > Step 2 - Append each additional track: > I moved an existing file out of the current directory > and into another: /media/sdc1/backups/rt/2008/02/ rt.2008.02.06.tgz > and added a new file: /media/sdc1/backups/rt/2008/02/ rt.2008.02.07.tgz > ... # growisofs -M /dev/hda -R -J /media/sdc1/backups/rt Your idea is great. Greater than genisoimage can fulfill currently. You cannot delete or rename a file by genisoimage multi-session. genisoimage will not examine a directory tree for changes and update it in the ISO image. Looks like it rather refused to overwrite some directory. Or it is just a bug. Hard to say. You should nevertheless be able to add a new file to an existing directory. Try whether this works as second session: growisofs -M /dev/hda -R -J /media/sdc1/backups/rt/2008/02/rt.2008.02.07.tgz (Use fresh media. Not those from previous experiments.) With cdrskin you would have to do what is usual with CD-R and multisession: c=$(cdrskin dev=/dev/hda -msinfo 2>/dev/null) mkisofs ... -C "$c" -M dev/hda ... | cdrskin dev=/dev/hda -multi -tao ... The libburnia project is quite near to releasing an integrated multi-session tool which would be able to do parts of your above sketch. For the remaining days - or if you have had enough adventure - i would advise you to either use above cdrskin gesture or to go back to growisofs which will do the same more conveniently. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
