Hi,
I want to reduce my booting time. I found a lot of articles on internet but I don't found a simple practical instructions , in particolar I need to reduce 'udev' time. Can you send me instructions ?
I send you my booting log with time , how you can see 'udev' time is 9 seconds !

I have a static system, I know my device at power on.
Where I have to change ? In kernel or file system or both ? Can you send me the simple instruction to modify the kernel or file system or both ?
