A large number, possibly a majority, of system calls in the os module, have "dir_fd" arguments that cause them to call the *at counterpart of the underlying system call. And chdir can also be called with a file descriptor, which will call fchdir (though there is also a fchdir function) I don't know why pipe2 was implemented as a separate call.
