Have you seen Mezzano? It's a pure Common Lisp Operating system, albeit there are few C programs that were transpiled to CL to run on top as well (IIRC, DOOM :D

Have you seen Mezzano? It's a pure Common Lisp Operating system, albeit there are few C programs that were transpiled to CL to run on top as well (IIRC, DOOM :D) It's somewhat limited but AFAIK it could in theory be made to self-host (right now IIRC image building is done separately from another system, but that's mostly a case of some programming work)
