initramfs-tools has updated and raspberry pi doesn’t like building them for custom kernels so you need to change a config. normally my kernel updates fix it. You can issue this command to fix it.
sudo sed -i '/^MODULES=dep/c\MODULES=most' "/etc/initramfs-tools/initramfs.conf"
Or you can reinstall the kernel
sudo apt reinstall clockworkpi-kernel
I need to put out a new image, they updated initramfs-tools right after I put out the last image.
