Linaro Ubuntu boot speed optimization

Registered by Ricardo Salveti

Continuous evaluation of the boot speed performance for the images supported by the Linaro Developer Platform Group. Optimization work is expected where feasible.

Image types:
 * Ubuntu LEB
 * Nano
 * Developer
 * ALIP

Reference:
 * Ubuntu ARM Boot Speed Optimization: https://blueprints.launchpad.net/ubuntu/+spec/other-o-arm-boot-speed
 * Blueprint for Natty: https://blueprints.launchpad.net/linaro/+spec/performance-linaro-n-boot

Work closely with the Ubuntu ARM team to avoid duplicate work.

Whiteboard

User Stories:
1. As a user I want to know what is the expected booting time for the Linaro images.

2. As a distro developer I want to know in a daily or weekly basis the boot report, to see if there's any regression and be able to identify possible areas of improvements over the cycles.

3. As a Linaro user I want to have the same boot performance improvements done for the official Ubuntu ARM images during Oneiric cycle.

Engineering Blueprints:
1 - Integrate the boot profiling tool at LAVA, making it report daily results with supported images
2 - Identify bottlenecks and improve the boot performance when possible
