Speeding up live cd boot through optimizing file layout

[Hervé Fache]

Not only does that speed up the boot process, it also increases the
life time of the optical drive, by diminishing the number of seeks
(moving the optical pick-up back and forth) it has to perform.

Indeed, moving the squashfs at the end of the CD might make for a
higher speed, as most optical drives work with constant angular speed
(or 2 or 3 angular speeds that depend on head position), and therefore
have higher linear speed on the external edge.

I think it's a good job. Good luck!
