I'm writing something sort of like that. 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).
