Boot Linux In Just One Second

In this years Embedded Linux Conference Europe, one interesting presentation was how-to boot Linux in just one second. Jan Altenberg of Linutronix presented how to achieve this feat of booting Linux in under one second. Linux as we know, became one of the most popular Embedded Operating Systems. Its scalability, the real-time capabilities and the excellent energy saving functions are outstanding. But there are still a couple of use cases where the usual power saving functions are not good enough: Automotive components usually need to be switched of for standby, because even the lowest power states of an embedded device are still consuming to much energy.
