Can't get kernel namelist
It doesn't work. There are tiny pieces of SVR4 and some number of pieces
of POSIX in NEXTSTEP but neither are especially complete, and you
shouldn't expect those interfaces to work even though sometimes some of
it does work "enough". OPENSTEP 4 is noticeably more complete in this
regard, but still pretty thin on the ground by modern standards (it was
thin on the ground by most people's standards even when OPENSTEP was
current).
There is, for example, enough of utsname to write your own 'uname'. I
had to do this once for some braindead autoconf script.
Generally, though, forget it.
I wonder if there's enough support under NeXTstep to get GNU Coreutils
compiled. Hmm.
Peace... Sridhar
