You don't need symlinks, you have a startscript that runs busybox ash,
then it will use all its applets, init included.

This way about all the openrc shell scripts is executed by the same
interpreter and sed/grep and such are just function calls and not
slightly more pricy fork+exec.

Doing this way you get a quite fast boot and depending on your needs you
can leverage more busybox applets to replace even more programs (e.g.
dhcpcd).

That would be the theoretical fastest boot possible short of integrating
start-stop-daemon in busybox.
