Boot time tuning chapter 5th: Timing

Hi everybody,

as promised I'm here again with another chapter about boot tuning. Last time I made a little step back to improve my system reliability, today I'm moving forth again, with no renounce of course!

The solution I was trying it is very customizable, but I'm going to explain as well as I can how can you achieve the same degree of optimization on your box. Our requisites are a text editor, bootchart and if you are running gentoo we will use eselect tool. If you don't have bootchart you can find a guide how to install it here or googling around.

As always I suggest you to give up if you don't know what you're doing, unless you try it on a "testbox". I don't take liability of any consequence.

Boot time tuning chapter 4th: Reliability

Hey,

today I'm making a little step back but another forward. I mean that in the last tuning chapter I was enthusiastic of my 9 sec boot time, even knowing I was on the edge of the blade. Actually nothing bad has happened, I was even able to cut away another second.

I did optimize booting levels and made some order in my xorg.conf. Maybe some little extra is given by the latest xorg version, which I installed in these days. At the very end of my optimization I was able to boot in 8s... but sometimes I was not able to boot. So here is the detailed story.

Boot time tuning chapter third: fastest boot ever 9s

Hey there. Amazing. I just got an incredible result. Boot time under 10s. I found a way to real optimization and full use of my box power. You can see my latest bootchart graph here. The steps are really painless but beware the result might be a not booting machine.

Please notice that the machine is not a micro-kernel eeePC or netbook or embedded device. It's a Core2Duo, 4GB Ram, OCZ Vertex serie SSD Laptop, MSI PR201, hand assembled and customized, but still a common PC.

The first ingredient of our soup will be OpenRC, seen few posts ago.

The rest is some luck (as it never hurts) and some risk-taking hand-made modifies.
