testing detached header failed:
1. built grub payload with following modules: ahci usb_keyboard part_msdos part_gpt at_keyboard cbfs cryptodisk luks2 lvm gcry_rijndael gcry_sha1 gcry_sha256 gcry_sha512 2. encrypt a partition: cryptsetup luksFormat --type luks2 -q -h sha512 -s 512 --pbkdf pbkdf2 --header /path/to/header --luks2-metadata-size=16k --luks2-keyslots-size=512k /dev/sda1 (where --luks2-metadata-size=16k --luks2-keyslots-size=512k is optional, this is just to minimize header size, but I also tested without). 3. from the grub cmd, i try to decrypt this partition using: cryptomount -H /path/to/header (ahci0,msdos1) 4. I also tried luks1 encryption with detached header. whatever I try, I always get the same error: "no cryptodisk module can handle this device" Is this feature not 100% implemented yet, I saw people already verifying the patches and would expect this to be working, so if yes, this seems like a bug.
