#2Russ Cox was involved in this, and also Go. There are important connections between them.

#4Apparently noteworthy because late last year they ported the original x86 to RISC-V.

Learn about Unix internals on something much smaller than the available alternatives?

#6Similar teaching operating systems include:
Blog OS, an operating system written in Rust constructed through a series of independent tutorials.[0]
The CS140E embedded operating system.[1] This OS comes from an experimental course taught by Dawson Engler at Standford. The instruction is lab-based with no lectures. The student builds the OS on a Raspberry Pi through the use of primary-source technical references like datasheets and ARM manuals.

The included textbook is _really_ good introduction to systems programming. I highly recommend taking a look if you are interested in kernel programming or interaction between OS.

#8PintOS is also a nice learning OS that's been used in classes. It is initially incomplete and there are 4 projects to implement process schedulling, paging, files. It simplifies the learning process since the hardware related initialization code is already implemented and is readable enough to be understood, while allowing you to focus on implementing the main ideas in OSs.
Currently I'm doing project 1 on my own. It would have been really nice if my university offered me something like this, to have instructor feedback.

The nice thing about xv6 is it gets a lot farther to be a full OS. User mode, ELF loader, an ascetic but usable system call table, etc.

In addition to teaching, it's been used as the core of a couple proprietary OSes for small envs. I think at least one TEE monitor is a heavily modified xv6.
