If you plan to use Grub 2.06 with LUKS2 note that:
> - Argon2id (cryptsetup default) and Argon2i PBKDFs are not supported (GRUB bug #59409), only PBKDF2 is.
> - grub-install does not support creating a core image that could be used for unlocking LUKS2.

Just had a hard long time debugging because I assumed full support which is not the case yet.

Also `grub-mkconfig` or `grub-install` do not bother to warn you about any incompatibility. The crypto commands are just silently omitted. 😑
