Debian, Ubuntu and all derivatives thereof use initramfs-tools, which does not use systemd in the initrd, and things work just fine

Ubuntu is literally trying to replace it with dracut as we speak.

Dracut is used both in Void Linux and on Alpine without systemd and with busybox.

It even runs continuous integration with musl based containers.

Alpine uses mkinitfs per default, tho.
