Description Stephan Wiesand 2007-05-26 13:22:45 UTC 
Description of problem:

If no label is found on a VFAT partition, the variable label is not touched at
all by the new code in mount/vfat.c. Consequently, mount thinks it has the same
label as the previous partition.

Version-Release number of selected component (if applicable):

util-linux-2.12a-16.EL4.25

How reproducible:

easily

Steps to Reproduce:
1. create two consecutive partitions
2. create an ext3 filesystem and a label on the first partition
3. create a VFAT filesystem without label on the second
4. create an fstab entry to mount the first one by label
5. mount -a
 
Actual results:

# mount -a
mount: LABEL=... duplicate - not mounted

Expected results:

this should work (and it does if one uses dosfslabel on the VFAT fs)

Additional info:

This breaks existing dual boot systems. Not uncommon.

The bug 240432 is not viewable by non-redhat employee's.
Can it be changed so it can be seen, or can the solution be posted to this bug
entry.
