Yup. The OP was talking about using e2label to change the label on an ISO9660 filesystem, which it cannot do. e2label deals with _filesystem_ labels on ext2, ext3 and ext4 filesystems ONLY. There is no filesystem label on ISO9660 images, but there IS an optional "volume" label, which may be set when the ISO image is created. There may even be a utility that lets you bugger the volume label on an already-created ISO image file (but ISO images are supposed to be read- only). Most commonly used read/write filesystems support filesystem labels. Ext2|3|4, XFS, BTRFS, NTFS, VFAT and a number of others all do. Some support longer labels than others (ext2|3|4 allows up to 16 characters, XFS only 12, etc.). Raw disks don't have labels. MBR partition tables do not support _partition_ labels. GPT partition tables DO support partition labels and one should note that GPT _partition_ labels are separate from any _filesystem_ labels applied to filesystems on those partitions. Here's an example from a 1TB USB drive I use for backups: [root@prophead ~]# parted /dev/sdb GNU Parted 3.2 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: Seagate BUP Slim SL (scsi) Disk /dev/sdb: 1000GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 1000GB 1000GB ext4 BackupDisk (parted) quit [root@prophead ~]# e2label /dev/sdb1 BackUps The output from parted shows partition 1 as having the _partition_ label "BackupDisk", but the output from e2label querying the ext4 filesystem on that partition comes up with a _filesystem_ label of "BackUps", showing that they are, indeed, separate entities. Please excuse my being so bombastic here. Just trying to be thorough. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - If this is the first day of the rest of my life... - - I'm in BIG trouble! - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx
