I think I read that it was based on CMU Mach -- is that right?

It did seem for a while that a lot of things were based on Mach, but
very few seemed to make it to market. NeXTstep and OSF/1, the only
version of which to ship AFAIK was DEC OSF/1 AXP, later Digital UNIX,
later Tru64.

MkLinux didn't get very far, either, did it?
