Nicely thought. Count me in for testing.

Do you think it would be possible to have something along the lines of

    ifconfig_em0="inet ..."   ( default (or unknown) runlevel )
    ifconfig_em0_foolevel="inet ..." ( foolevel runlevel )
    ifconfig_em0_maintenance="inet ..." ( maintanence runlevel )

too ?
