joliet tree sort failed

[William_Olbrys]

following the remastering howto on knoppix.net i finished my custom cd and am trying to create an iso with mkisofs. I get the following error:

mkisofs: Error: /mnt/hda1/knx/master/KNOPPIX/source/KNOPPIX/var/lib/apt/lists/partial/ftp.gwdg.de_pub_languages_java_linux_debian_dists_ woody_non-free_binary-i386_Release and /mnt/hda1/knx/master/KNOPPIX/source/KNOPPIX/var/lib/apt/lists/partial/ftp.gwdg.de_pub_languages_java_linux_debian_dists_ woody_non-free_source_Release have the same Joliet name

after two or three of these errors the program stops and i get the error "joliet tree sort failed"

what are the master and source directories exactly? why is this error occurring?

nevermind i got it, i had to add the -joliet-long option to the command.
