Public bug reported:

Installing a minimal system with the following setup:

/: btrfs or ext4 encrypted
/boot/efi: fat32 unencrypted

leads to a system that does not boot.

Apparently either grub is not correctly set up or the filesystem is
encrypted in a way that grub cannot handle.

Grub drops down to the interactive grub-shell.

Entering `normal` shows an error message for the fraction of a second:

"error: no such cryptodisk found. perhaps a needed disk or cryptodisk
module is not loaded."


Note:

Adding an unencrypted /boot-filesystem does work. However the installer
will heavily suggest not doing that (and probably rightfully so).
