Subject: Grub installation only checks for encrypted /boot folder
Date: Mon, 21 Oct 2019 13:07:09 +0200

Hi,

The following configuration results in an unbootable system.  The
root partition must be manually mounted with cryptomount in order to
boot the system.

The core issue is that grub unencrypts automatically, as
GRUB_ENABLE_CRYPTODISK=y was provided during installation, the /boot
partition, but not the partition which contains /gnu/store.

Happy hacking!
Miguel
