Could you check whether your system configuration's 
bootloader-configuration actually contains a keyboard-layout 
field?

       (bootloader (bootloader-configuration
                     (bootloader grub-efi-bootloader)
                     (target "/boot/efi")
       -->           (keyboard-layout keyboard-layout)))

The last time I tried adding this myself (granted: that was a year 
ago) it broke my GRUB, so today I still type my passphrase once in 
Qwerty and once in Dvorak.  Much secure!

Kind regards,
