Not really. It doesn't support symbolic links. Or select() using any
file descriptors other than a network socket. Unix domain sockets are not
supported. cp -r isn't there either. Actually, the TCP/IP is an expensive
option - as normally distributed, all the functions like socket(), connect(),
etc. return an error (Unimplemented system call or something like that).
Oh, and some of the TCP/IP socket function interfaces are slightly different
than 4.2 (I can't recall the specifics right now)
Oh, it DOES have C-shell. However, the kernal does NOT recognize "#!",
which limits the usefulness of csh scripts.
I would rather have berkeley 4.2, but we really need shared memory.
