• Encrypting a data volume with LUKS2: format, open, crypttab, and what a lost header means

  cryptsetup luksFormat and luksOpen set up and unlock a LUKS2 volume, and /etc/crypttab makes the unlock happen automatically at boot; a lost passphrase and a lost or damaged LUKS header are both unrecoverable, which is why luksHeaderBackup is a required step, not an optional one.
