I made a small busybox based statically compiled distro which used busybox init, busybox init is basically just a bunch of shell scripts

Busybox init is a binary. It can run anything (based on /etc/inittab) incl. other binaries. There's no need for it to run shell scripts (other than /etc/inittab lines which are executed under `sh -c "..."`).
