    Out of curiosity: might it be more valuable in the long run to
    implement a sort of an `su.conf' in /etc which could contain expansions
    for SU_GROUP and ROOT_AUTH? Combined with more su configurability for
    logging, this would make su a good replacement for sudo for many
    users...

    OTOH, there's a strong argument to keep something as security-critical
    as su as bone simple as is possible...

    Thoughts?
