Block device configuration:

I have a fully encrypted system (except the EFI partition) with a separate /boot (LUKS1 encrypted) partition and a LUKS2 encrypted PV for the LVM group. All the themes, fonts (and encryption keys for the PV) are stored on the /boot partition. There is no need to decrypt the PV in grub stage of boot, the initramfs will have all the information to do it.

The issue:

The grub configuration will make grub to, correctly, ask me first for the password to the /boot, and then, immediately after and erroneously, for the password to the PV.

The "investigation":

In the 00_header, the initial part of the /boot/grub/grub.cfg is created. This includes the fonts and the themes and their locations. The 00_header trawls the configuration in /etc/default/grub for the location of the theme. Then takes the name of the theme, disregards the given location and searches for the theme in "known" locations and uses the first found: /usr/share/desktop-base/grub-themes/. This results with the / being used, and therefore makes it necessary to decrypt the PV it resides on.

The proposal for fix:
Changing the order in which the "known" locations are searched for the theme fixes the issue. For an example see the attached file.
