Package: dosfstools
Version: 3.0.3-1
Severity: normal

When you use dosfslabel to relabel an MS-DOS block device,
it updates the primary supeblock but not the backup
superblocks. This is evident if you perform something like

    mkfs.msdos -n JMTD_LABEL_1 /dev/ram0
    hd /dev/ram0  > ~/hd_before
    dosfslabel /dev/ram0 JMTDLABEL2
    hd /dev/ram0  > ~/hd_after

Note that the label I chose at first was truncated hence
the form of the second label.

    diff -u ~/hd_{before,after}

This demonstrates the label updated in the primary
superblock.

    grep JMTD ~/hd_after

This demonstrates the old label still present in a backup
superblock.

If you setup a new filesystem to mount at boot and then use
dosfslabel to change its label, on reboot an fsck run for
that filesystem is forced by the differing superblocks.

Then I searched the first dosfstools release that works correct. The version
3.0.7 is the first version for which everything works as it should.

thanks for looking it up, closing the bug now.
