LPC: Booting Linux in five seconds

Just FYI, historically servers have driven a lot of the, for instance, hardware changes necessary to get fast boot (ever noticed that default POST started skipping a number of mostly-useless checks in the last few years?). Mostly because people wanted be able to write big enterprise contracts saying "the server will be up 99.999% of the time", which gives you 5.2 minutes downtime per year, and if one reboot blows your yearly downtime budget, well...

(As far as I know no-one no-one cares about +-minute of reboot time in practice and the whole 99.999% thing is largely a gimmick, but you need it to be Marketing Compliant(TM), and apparently that's enough to drive BIOS changes etc. And hey, faster boots for us.)
