>Description:
        /usr/mdec/mbr_bootsel of recent -current changed its behavior
        in that it no longer successfully auto boots its default
        configuration. Instead it displays a '?' after showing its
        menu and timeout in the same manner as if a false key was
        pressed in the meantime.
        Pressing a correct key after that makes mbr_bootsel proceed
        booting in the correct/intended way.
>How-To-Repeat:
        Install -current's mbr_bootsel (with several (I have 3) boot
        menu entries and a correct boot config) and see how it
        fails/stops booting the default config after its timeout.
>Fix:
        Workarounds:
        - Use an older mbr_bootsel (of Nov 28th 2007 works fine).
        - Manually press the key for the intended partition. :-/
