Investigate speeding up the casper boot process
Investigate whether it is possible to clean-up and speed-up the casper boot process for live-cd images. Currently live-cd's boot slower on ARM than on x86 and this spec is to discover what the bottle necks are and to come up with solutions to fix them.

Whiteboard
[asac 25-11-09] - seems to be on track - lets review if there is anything that can be improved when the first TODOs are done.
[asac 01-12-09] - targeting the investigation part of this spec for alpha-2 .. fixes can take till final.
Status:
Solution implemented and available in archive.
