s6-linux-init [1] does not provide a replacement for /sbin/init, but
a tool to generate one FROM the target. So when this package is selected,
there is no risk of messing up target/sbin/init at build time. Hence no
need to make it depend on on BR2_INIT_NONE.

The s6* packages provide the tools to build an init system with service
supervision (as the author states it: "mechanism over policy"). It is up
to the user to glue everything via post-build scripts or a custom
skeleton. A basic example of such a skeleton [2] is available in a
personal Buildroot external customization [3].

Should some comments be added in s6-linux-init/Config.in to clarify
this?
