    Changing Linux behavior would violate the POSIX and SuSV2
    specifications; the standards explicitly state that the working
    directory will NOT change. And standards adherance is important; we
    break them only if we have a d*mn good reason. And trying to make
    chroot() something which it is not (i.e., a secure jail) is certainly
    not a good enough reason.

    Can we please end this thread now? And can we put in a Kernel FAQ
    saying that this is not something which is NOT up for discussion?
