Subject: bug: blkid doesn't notice when fs labels change to blank
Date: Sat, 6 Oct 2012 10:58:46 +0100	[thread overview]
Message-ID: <CAMU1PDjWg3AG+V86MmDUC7X-+_DbHhxda_fMSqL9P-do4wC6uA@mail.gmail.com> (raw)

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
