Reboot like a racecar with kexec
If you have ever found yourself in the position of having to reboot quickly or several times, you know that it's not a very quick process, particularly if you have SCSI devices or other initialization-intensive system devices. A package called kexec can speed up your reboots -- if you understand the rules. Kexec was originally intended for use by kernel and system developers who had to reboot several times a day. Soon, system administrators for high-availability servers found use for it as well. As systems get more and more advanced, and boot times get longer, end users can now benefit from it.
