The initial configuration will never have huge_pages enabled.
If you want that, it's up to you to adjust the settings
afterwards --- and that typically would also involve changing
shared_buffers.  (The settings that initdb would choose are
not large enough to justify worrying about huge pages anyway.)

This claim is quite detail-free, so I don't see how we are
supposed to respond to it.
