                   Red Hat, Inc. Bug Fix Advisory

Synopsis:          mount and e2fsprogs fail when using 16 character labels
Advisory ID:       RHBA-2000:074-02

1. Topic:

Red Hat Linux 7.0 uses volume labels instead of device names by default in /etc/fstab. However, mount cannot deal with labels equal to 16 characters, making a system which defines long labels unbootable.

2. Relevant releases/architectures:

Red Hat Linux 7.0 - i386

3. Problem description:

In Red Hat Linux 7.0, /etc/fstab uses ext2 volume labels instead of device names for defining mountpoints. For example, a line such as:

LABEL=/                 /                       ext2    defaults        1 1
is written to mount the root filesystem.

However, the mount command, as well as other ext2 commands, don't handle labels that are exactly 16 characters long. They properly deal with labels 15 characters and less.

If your /etc/fstab contained long volume labels, your system would be unbootable, as mount would fail on these partitions. This release fixes all known problems with volume labels.

4. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.
