"And no cheating. "Done booting means CPU and disk idle," Arjan
said. No fair putting up the desktop while still starting services
behind the scenes. (An audience member pointed out that Microsoft
does this.) The "done booting" time did not include bringing up the
network, but did include starting NetworkManager. A system with a
conventional hard disk will have to take longer to start up: Arjan
said he has run the same load on a ThinkPad and achieved a
10-second boot time."
