I should also say that, since the subject is "...label of an iso9660 file system", the label for an ISO9660 filesystem is actually a volume label, set during image creation via the "-V <text>" option of the xorrisofs command. Again, "e2label" inserts a label into the partition table and superblock for ext2|3|4 filesystems, not on the host block device that holds them. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ri...@alldigital.com - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - Always remember you're unique, just like everyone else. - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
