LPC: Booting Linux in five seconds

Also, suspending is not the same as booting when it comes to your
applications. I can suspend my notebook by closing its lid, and when I
come back every single program is exactly where I left it (except for
those that depend on network sockets). This is way better than shutting
down and rebooting; even apps that support session management don't do
that well compared to a nice suspend/resume.
