OpenBSD boots multi-user on Apple M1 hardware

Is there something about multi-user that makes it harder than single-user? If it boots, it's all software at that point, no?

Implies a level of stability greater than getting to the "press enter for sh" prompt. Virtual memory is working, filesytems are working, etc.

Also probably tests things like signals/job control. I ran into an issue bootstrapping ppcle (on linux) where everything but the signal handler (and vDSO) were working, but context switching from a kernel to a signal handler ended in SIGILL. Booting multi-user probably wouldn't work without working signals.

In the sense that single user mode is used as a failure mode for the boot process, it indicates that the system was successfully able to bootstrap from the EFI to its own (critical) drivers successfully.

lots more context switching which is a big thing on a new architecture.

It goes from "it boots as a toy" to "actually useful"
