It's certainly what I had in mind when I started the project. Writing a full Lisp operating system is extremely hard, better to take advantage of Linux and its drivers so as to avoid spending an entire lifetime recreating them.
It's my understanding that a true Lisp machine would have hardware support for Lisp abstractions at the instruction set level, so I don't think the concept would apply to lone. I would be seriously honored if people considered it one though, even if only in spirit.
Well, if by lisp machine we understand a processor that can run native lisp, of course not, but I was dreaming with a modern lisp machine, and this is the best that can be practically made
