The project seems orphaned. I never heard about it before. It's still referenced here as an option to run Genode OS: https://genode.org/about/index

Thanks, had almost no idea what I was even looking at with the reference. Originally thought maybe it was some weird academic variant of Linux.

After a bit of searching, apparently it's part of the L4 OS family. (More Unix) Wikipedia has a summary in the L4 microkernel family article.
