The following is my

We can see that mounting
ext4 takes nearly 13 seconds.
Is it mounting that takes 13 seconds or the
udevd that takes 13 seconds?
udevd is initiated again around 21 second. Why is it that
udev is started twice?
How do I optimize this feature? Any pointers on how I can approach this?
I run a custom
3.12.4 kernel, that I optimized for size, and my OS is Ubuntu 12.10
