    smgl.init: improved boot media selection algo
    
    Improved the algorithms for how the initrd selects the media to boot
    from. It will now use /sys instead of /proc to autodetect removable
    media and try those for booting. I also added the missing boot-from
    function so that users can now properly override the boot media
    autodetection and force the initrd to try booting from a
    user-specified device.
