    Better, apparently to "copy" (not actually), rather than to whine in the
    background...

    Still - your response is equally ignorant (Plan 9 is well known - even
    to students), since it offers no useful information.

    The /proc stuff is used in "real" Unix's such as Solaris. Just checking,
    I see that FreeBSD implements procfs, which is along the same lines.

    (still waiting for FreeBSD to "complete" a sysinstall program that doesn't
    look as if it was an assignment for high-school interns).
