In the embedded space, quick boot is a really important feature to
have. Many people resort to awful hacks in order to improve boot time,
and so I would welcome this option.

I have seen arm systems that boot in 300 ms. I would say that 50 ms is
maybe not such a small improvement after all.

Thanks,
