Linux Lennart Poettering, the author of systemd, has announced: "I just put a first version of a wiki document together that lists a couple of easy optimizations to get your boot times down to [less than] 2s. It also includes a list of suggested things to hack on to get even quicker boot-ups."

The document specifies that it works best on systems with SSDs. IOW computers that will boot in a few seconds using a normal init system. A 2-second boot on a machine with an SSD is not what I'd consider a big win.

I'll also note that

a) Last time I set up Arch Linux on my netbook - using sysvinit, and a normal hard disk drive - it booted to the login screen in about 10 seconds. This wasn't a major feat either, all I had to do was customize the initrd and background a few daemons.

b) Boot time contests don't matter, because desktop environments like Gnome 3 and KDE 4 have bloated to the point that login is now slower than the rest of the boot process. Right now Ubuntu can take 20 seconds to get to the login screen, and 30 to get Unity into a usable state.

(And I don't know about you, but I care about the login time more than the boot time.)

I have an Atom netbook (maybe 4 yrs old now) with which I occasionally swap the storage drives. SSD runs Debian Sid and the stock 5400rpm HDD runs Arch Linux.

Arch + systemd alone wasn't that great, but Arch + systemd + e4rat (only works with ext4) gives me around 7sec from GRUB to prompt. Login time is a usually 1 - 1.5 sec after I do "startx", since I run lightweight tiling WMs most of the time.

You might want to check out the ArchWiki's e4rat page if you're on ext4 on a regular HDD.

I actually care more about my computers hibernation state even more than the boot time. I would rather not have to reboot my laptop, however after a few sleep sessions. My resources start to fade away.

From login screen to usable unity takes ~15 seconds for me.
