I could be totally wrong with that assumption, but take a look here:
There is stated the LUKS-Header is containing the UUID of the crypted
partition in Hex-Format starting from offset #168.
This would mean, even you are saving LUKS-Headers and restore them, the
UUID of the Header-Entry must be changed also if you restore to a
different disk than the original one.
If this is the case, the scripts could get the uuid of the /boot
partition, write it in rescue/ and compare it at recovery.
This should be always the case with dm-crypt/LUKS. Am I talking BS?
