The kernel tries to find init in various locations (/sbin/init,
/etc/init, /bin/init, etc.). If it can't execute any of those, then
the kernel panics. You just removed Busybox init, so you are left
without init process to load.

One way to override kernel search is passing init= option as you did.
You can put that option in the bootloader options and get done, or you
can symlink systemd (or what you want to load) in /sbin/init so the
kernel can find it in the "standard" location.

HTH,
