    In practice we have to extensively customise policy long before getting to the
    non-proc stage of optimising for small hardware. The Familiar distribution
    (used on the iPaQ) has /proc but needs significant policy changes when
    compared to a typical Fedora workstation. Not only is there the issue that
    embedded distributions have different daemons and path names to workstations,
    but the memory constraints mean that even a modular targeted policy is not as
    small as you desire.

    I think that is the correct thing to do. Someone who is prepared to do all
    the work needed to get a recent SE Linux system operating without /proc will
    have no problem changing the kernel config scripts and everyone else would be
    better off not being confused by being offered sets of options that are not
    viable.
