For context:
I’ve encrypted the swap partition with:

cryptsetup -v luksFormat /dev/${DEVICE}
cryptsetup luksOpen /dev/${DEVICE} swap

And what I want is for the user to be able to enter their password only once to decrypt their root partition which would contain a keyfile to then decrypt their swap partition.

Does anyone know if this is possible?
Just thought I’d ask to see if anyone’s done this already

    I have home and root partitions encrypted with LUKS, and since they use the same password it automatically unlocks both of them. I think it tries using the first successful password to unlock the other partitions.
