How Kernel Hackers Boosted the Speed of Desktop Linux
chromatic writes "Kernel hackers Arjan van de Ven and Auke Kok showed off Linux booting in five seconds at last month's Linux Plumbers Conference. Arjan and other hackers have already improved the Linux user experience by reducing power consumption and latency. O'Reilly News interviewed him about his work on improving the Linux experience with PowerTOP, LatencyTOP, and Five-Second Boot."
actually we do bring up the network daemon (either connmand or network manager) as soon as we can, but we don't stop the entire startup process.
on my test system here it runs dhclient about when X starts up and the network card receives a reply with a few seconds from that, long before I can start firefox :)
we don't even need to recompile the kernel, we can just link the modules in as needed. Something most older UNIX systems actually did.
