I agree, adding 2 seconds to boot time wouldn't be very well received.
Our board has several gpio buttons which are checked for a specific press
configuration at startup, eg, when buttons 1,3 and 4 only are held down, the
auto boot is delayed.
This is obviously dependent on board hardware, but does make any delay
optional.
This is in our init script itself, but could just as easily be coded to check
before the init script is run. You could set it up as a board installed
callback...
Cheers,
Marc
