    Well, the latest version of the memory detection code kills a couple
    of machines, so it's probably just as well that it isn't in the
    mainline kernel but instead crashing a couple of obsolete or
    hideously expensive motherboards that I can't find or don't wish to
    raid the LART-farm account for.

    In any case, there *is* a BSD-style configurator for Linux, though
    it hasn't been maintained since 1.2.x -- Scott Telford wrote one for
    Linux years ago, and it died when he bailed on Linux in favor of the
    *BSDs. It plus mconfig (which is written in C, which wins bigtime
    because it's not extra programs that I have to lug around to make a
    Mastodon system self-compilable) would make an almost perfect pair,
    even if the underlying data structures are a little bit grotty.

    The whoops-time-to-fork-the-linux-kernel showstopper for me is that
    the reference implementation of this new configuration language is
    written in Python, and, given the fluidity of linux kernel
    development and the impossibility of getting patches to Linus unless
    you're a member of the Core Team, this would probably mean that the
    Python implementation would be the only implementation that would
    ever work.

    david parsons \bi/ I can see using perl or python to parse a real BSD
                   \/ config file (though I'm trying to do it in C), but
                       the Linux kernel configuration arrangement is fairly
                                    simple and, thanks to MEC, fairly clean.
