It works the same way as other init systems:

If you use an initramfs, the kernel looks for an /init program inside,
and executes it as PID 1. (The initramfs /init then mounts real root
and exec's /sbin/init found there.)

Without an initramfs, the kernel looks for /sbin/init, /etc/init,
/bin/init directly on the root filesystem (can be overridden using the
init=... option)

(The initramfs /init itself can be systemd, though most distros have
it as just a shell script.)

Try the boot options loglevel=6, systemd.log_level=debug, or init=/bin/sh.
