Subject: [PATCH 1/2] IS_DUPLICATE_FS_LABEL: blkid has a cache that can provoke
 false positive

Disable the cache by using `-c /dev/null`.

Example of false positive:

```
/dev/mapper/HDD0-swap2: LABEL="SWAP2" UUID="5540a49e-3e7b-4528-9c4e-49fb5f8d7f3d" TYPE="swap"
/dev/dm-0: LABEL="SWAP2" UUID="5540a49e-3e7b-4528-9c4e-49fb5f8d7f3d" TYPE="swap"
```

`dm-0` may have been cached during boot time, if you don't use a cache,
it doesn't appear any more.
