/ on LVM isn't all that useful, simply because it's size doesn't change
much and there's no real need to grow it. It's not like /var.

Binary distros put LVm on / not because it's a good idea but because
they like to have consistency. You don't need that because you know
what you built and it doesn't need to be supported by a corporate
employee far away.

You are worrying yourself needlessly about this init thing.

Just take some small measures to ensure that it will never be a factor.
