Specifically it will be a QNX-like OS in which literally everything is a file (even all process state and memory), with pretty much the only real primitives being variants of read()/write(), and everything else will be built on top of those (even other file APIs like open()/close()/stat()). The user-level API will be mostly compatible with conventional Unix, but will be split into multiple libraries rather than throwing everything in libc (there will be a base system library implementing the core file API, and libc and a few other libraries implementing a relatively standard Unix API will sit on top of this).
