Hi,
When the label of a file system is changed from something to blank,
blkid doesn't recognise that change.
Test case:
# mkfs.ext4 -L test_label /dev/sda15
# blkid /dev/sda15
/dev/sda15: LABEL="test_label"
UUID="81d5f9cf-01eb-4861-b284-ea4fa4e92a3f" TYPE="ext4"
# tune2fs -L '' /dev/sda15
# tune2fs -l /dev/sda15 | grep 'Filesystem volume name'
Filesystem volume name: <none>
# blkid /dev/sda15
/dev/sda15: LABEL="test_label"
UUID="81d5f9cf-01eb-4861-b284-ea4fa4e92a3f" TYPE="ext4
This seems true regardless of the file system type used.
Thanks,
Mike
