Note: "permalinks" may not be as permanent as we would like,

The alignment may also change depending on the metadata type of the md
RAID device. From the man page "The different sub-versions store the
superblock at  different  locations  on  the device,  either  at  the
end (for 1.0), at the start (for 1.1) or 4K from the start (for 1.2)."
