LINUX can boot in just 5 seconds

fastboot-f5Yes, its true that LINUX can boot in just 5 seconds (faster than multimedia synchronization) and its proved by two LINUX developers named Arjan van de Ven and Auke Kok. How did they proved it and how this could be happened, what was the hardware they were using etc, etc. There were many questions and they were simply awesome to answer them without any problem. Check the under given picture to see what was going on and then I will share a link with the complete questions and answers to meet the requirement and give you a clear picture of this article.

How they did it: readahead and init

Fedora uses Upstart as a replacement for the historic "init" that traditionally is the first user space program to run. But the Intel team went back to the original init. The order of tasks that init handles is modified to do three things at the same time: first, an "sReadahead" process, to read blocks from disk so that they’re cached in memory, second, the critical path: file system check, then the D-Bus inter-process communication system, then X, then the desktop. And the third set of programs to start is the Hardware Abstraction Layer (HAL), then the udev manager for hot-plugged devices, then networking. udev is used only to support devices that might be added later—the system has a persistent, old-school /dev directory so that boot doesn’t depend on udev; For complete article please open the under given URL;
