porting the nitro init system

[Emile `iMil' Heitor <imil%home.imil.net@localhost>]

Hi,

I'm working on porting nitro https://github.com/leahneukirchen/nitro to
NetBSD, the code is already pretty good and portable, but I am
struggling at finding "the right way" of doing something.
I want to be able to use nitro as a direct replacement for init(8) (just
for fun, don't worry), thing is nitro relies on either:

- /run for Linux systems
- /var/run for others

It uses those directories to create a control socket before anything
else.
NetBSD boots read-only, and at this stage of the boot, nothing is
writable yet, but no problem, we can use mount(2) to create a tmpfs
filesystem just for that. OK, but where?
/var and /tmp could be later mounted by fstab other mountpoints.
Creating a dedicated /run directory works but doesn't feel right.

Any correct idea comes to mind?
