devlabel
Devlabel is a program which dynamically creates symbolic links to disk/partition names. It uses the disk's and/or partition's unique identifiers to keep the symlink pointed to the correct location even if the underlying partition's name has changed. So, regardless of whether /dev/sdb6 becomes /dev/sdc6, devlabel figures this all out and points the symlink to the correct data.

Changes: This release fixes UUID handling of JFS partitions. Even though JFS itself is now considered version 2, it was only marking the partitions as version 2 if it was using an external journal. Thus, devlabel was seeing some version 2 JFS partitions as version 1 and was returning bad uuids (all zeroes). This new version works around this. Also, this version includes a fix for determining the UUID for partitions with no filesystem which are the 10th or greater on a disk.

Changes: Support was added for reiserfs filesystem UUIDs. If you have previously added symlinks to your reiserfs partitions, you'll need to re-add them with this version so that it makes use of the new identifiers.

Changes: This release makes sure to clean up temp files. Hard-coded paths to external programs have been removed in order to help cross-distribution usage.

Changes: This release automatically filters out regular-expression type characters from UUIDs. Thus any character of the set $,^,*,=,[,/,\ is transformed into a "_". This fix was requested in Red Hat Bugzilla #113107.

Changes: In this release, scsi_unique_id has been fixed so that it only looks for page83/page80 information if it is supported.

The new Red Hat Linux Version 9 uses devlabel.
The author of devlabel wrote a good White Paper that explain the function of the utility.
