I wonder how they plan to implement systems level programing features from Common Lisp on top of Lua.

I'm not familiar with Common Lisp or its systems programming features, but they can access any C API through LuaJIT FFI: https://luajit.org/ext_ffi.html

LuaJIT is so good that it is actually able to inline calls to C on the generated native code
