Yes, it's a plan9 port; why would you expect it to change any more than is absolutely needed to get it running on the new host OS?

I don't think it's a lack of comprehension, so much as that we disagree what a "port" means.

I was correcting the user's "plan9" comment.

It's a port of a collection of plan 9 userspace to a non-9 operating system.

Perhaps you've now learnt something
