There have been many talks about boot-time optimization in the past. For the most part, the only goal was a minimum boot-time. It's a good way to show the optimization techniques and gives a nice wow effect. But the end result is rarely usable in real world projects. So instead of looking for new ways to reduce the boot-time just a little bit more, this talk will look at boot-time optimization in a larger context. "The device needs to boot faster" is often stated but the actual requirements behind this are often more complex. We will look at typical requirements and possible solutions beyond general boot-time optimization. And while booting as fast as possible is nice, in most cases there are other more important requirements, which are often related to security or reliability. This talk will look at possible optimizations in this context. What are the consequences of an optimization and what trade-offs are possible? And last but not least, let's talk about the hardware. The choices made while designing a device can have a big impact on the boot-time. Therefore this talk will end with advices for hardware design criteria and component decisions to keep in mind to boot fast.
