I've run "dracut --no-kernel" in a minimal lxc container, once with pkg-config and once without and then diffoscope'd the two generated initrds. Most of what diffoscope complains about are timestamp differences in directories and symlinks which I don't know how to get rid of, but there's some changes in etc/conf.d/systemd.conf that I have attached. Not sure whether those are problematic?
