Bug Description
see upstream bug https:/
fix https:/
udev calls libblkid with flag BLKID_SUBLKS_
data in filesystem could be detected as broken superblock of other filesystem:
root@vla2-4101:~# wipefs -n /dev/sdf2
offset type
-------
0xae9c36ff006 nilfs2 [filesystem]
2019-02-14 05:
0x438 ext4 [filesystem]
normal blkid is fine
root@vla2-4101:~# blkid -p /dev/sdf2
/dev/sdf2: LABEL="/yt/disk5" UUID="778742b8-
builtin blkid sees two different superblocks and cannot decide
