Which approach do you think is better, and why?
Or do you think there is an even better way to use a hardware security token to unlock drives having LUKS full disk encryption?

wouldn’t doing this require that building a ram disk image with the yubikey software included?
All 3 mechanisms are native to a yubikey, and do not require yubikey-specific software/drivers to function as they use USB standards like FIDO2, keyboard for HMAC, and PIV/CCID for OpenPGP.
FIDO2 is built-in out-of-the-box, HMAC just requires adding the key to HMAC on slot 1 or 2 (tap vs long-hold key-inputs) using the personalization tool, or using gpg(2) to card-edit for OpenPGP.
None of these require YK software to operate.
Which of the 4 recipes I posted are you referring to as “this”?
read them and you will see that only ones mentions initrd at all.
I read them before writing my OP. I’m still not sure what you’re getting at.
I would be grateful if you could say what you mean, instead of initiating an oblique guessing game.
i don’t understand the hostility.
i asked a question about needing yubikey software in a ramdisk image to enable decryption at boot time and most of the sources you provided don’t mention it at all.
It’s not mentioned because it’s not required, yubikeys in general mostly leverage pre-existing “smartcard” facilities
Bystander observation: you were asked to clarify but essentially refused in a way that took more effort than simply doing so.
Oic. They didn’t understand that I was asking a question and thought that I was addressing one of their links
Thanks for helping clarify.
