The issue is the plymouth package. This was not auto-removed during image creation since somehow on Raspbian Stretch repo the mountall is available and marked as "required", so survives any auto-removal. On Debian Stretch this package is not even available: https://packages.debian.org/search?sear ... s=mountall
This package also requires initramfs-tools, thus this is not auto-removed as well. So we finally have an initramfs implementation and a splash screen implementation on RPi that is not required, since RPi has it's own implementation for both features...

Simple fix:
Code: Select all
G_AGP mountall && G_AGA
And if you already touch things, to resolve a potential service startup issue:
Code: Select all
sed -i '/^After=/s/[[:blank:]]multi-user.target//' /etc/systemd/system/dietpi-postboot.service
systemctl daemon-reload
