Five-second boot time demonstrated, sent to Moblin project


LinuxbootchartI might be in the minority when I say that mobile device boot time doesn’t matter, but I can’t help to notice this project. A few weeks ago, two Linux developers demonstrated a five-second boot time on an Asus Eee PC with Solid State Disk. The entire approach wasn’t to make a device boot faster, but to break the five second barrier.The developers started by used a tool called Bootchart to monitor how long each step of the boot process took. Fedora was up and running out of the box in 45 seconds. Taking that information, the developers modified the kernel to start in one second by cutting modules and optimizing those that made the cut. They also added a patch to allow the kernel to read ahead data blocks from disk and get them into memory quicker.While there’s some debate on whether or not all needed services are available in the scant five-seconds, it’s still pretty impressive. The project info and results are expected to help Moblin, the Intel-backed Linux environment for Mobile Internet Devices. I’m beginning to doubt that the MID market as originally envisioned by Intel is ever going to take off in widespread fashion, but if it does, you just might see sub-five-second device boots. While we wait, I’ll stick with Sleep and Resume.(via GottaBeMobile)



Fast booting is good.
I don’t understand why people are trolling and keep talking about how unnecessary it is blablabla sleep blablabla hibernate.
Lasy I checked it takes MUCH MUCH longer to sleep and/or hibernate than 5 seconds.
I take booting in 5 seconds any day over sleep and hibernate.


You’re not in the minority on this. Whenever I google for info about how to do fast booting, results are clogged with irrelevant comments from people insisting that we somehow don’t need fast boot because the commenter rarely boots.

They often patiently explain that a thing called sleep or hibernation exists. I don’t even think they’re intentionally trolling. It’s just the natural reaction of someone so completely self-centered that they can not imagine situations outside their daily experiences.

Jonathan, I agree but I don’t foresee 5-second boots in a full computing environment in the very near future. That’s why I’m sticking with Sleep and Resume for now. There’s a definite battery drain on devices when sleeping since the RAM requires a small amount of power to keep the environment retained, so your point is well taken.

With a 5 second boot time, I’d be much more likely to shut down over sleep which would save some power over the course of the day.

5 seconds is 4.8 seconds too many for regular use, but that’s *very* good for a device reset time.

I’d still want to stick with sleep/hibernate in most cases no matter what, but when you’ve got to reboot the system due to a firmware upgrade, some massively horked software, or a kernel panic, 5 seconds is pretty damned tolerable.
