Data-at-rest encryption ensures that files are always stored on disk in an encrypted form. The drive will use a boot partition which will remain unencrypted with a second partition which will be encrypted with luks and then use lvm to create volumes within the lux encrypted partition. But it has a few disadvantages: Once in a while, I need to install Archlinux on a new machine. Notes. Any attempt to clear the CMOS to clear the password will change the PCR 0 measurement (and probably PCR 7 as I think it resets the Secure Boot keys when you clear the CMOS, not sure on that, don't quote me), and TPM2 unlocking will fail, leading you to need to It allows to have deniable encryption (LUKS header on USB key, laptop's SSD is entirely encrypted), two-factor authorization (you can't load without LUKS header which is encrypted with your password).
