initramfs:/etc/fstab empty (efibootguard)

Hello.   I am using efibootguard and it is generating an empty fstab in the 
initramfs.  In an attempt to understand why, I wanted to just try and 
rebuilding the initramfs myself, then create the kernel again using 
bg_gen_unified_kernel, but I cannot even build the initramfs from the image 
because there is no /boot/config-* files.  

can someone help me understand where and how the initramfs and unified 
kernel is created in these recipes?

thanks

The related recipes are part of isar-cip-core which is discussed on
cip-dev@lists.cip-project.org. Please describe over there which steps
you exactly took and which layer versions and configurations you used.
