i use architect why i need an lvm-luks with unencrypted /boot. I need the german keyboard layout, while complex password-phrase with no equivalent on us keyboard and why i hope that in the next version comes a graphical luks/dm-crypt input;).
So architect let correctly grub_enable_cryptodisk=y disabled (#grub_enable_cryptodisk=y) but update-grub don't find the theme and don't generate the needed theme installations confs in /boot/grub/grub.d.
When i enable grub_enable_cryptodisk=y then update-grub find an theme and install an correct graphical theme.
A bug in the generation scripts from grub?
