Soo... I currently have:

• NetBSD sets mounted read-only
• Store-like, hand-made stuff mounted
• Persistence mounted
• Persistence's /etc layered on top of NetBSD's etc
• dinit booting into a system that has getty on constty for root login

I basically have all the tools to make a bootable system that then I can use to develop itself. It's not there yet, because at a minimum, I need a network, and either ssh or git. Since ssh is in the NetBSD base, that's a whole lot easier.

With ssh, I can TRAMP into the system and edit the code. I can't commit locally, but I can edit things remotely, and that's good enough.

...except I don't have a user yet. Oops.
