Optimized Live CD layout for faster boot

Registered by Krzysztof Lichota

Live CD boot time can be shortened significantly by laying out files on CD (or more precisely in SquashFS image) in such way, that CD-ROM head movements are minimized.

Whiteboard

mdz: approved 2006-06-20, but I suggest revising your time estimate. I think this will take longer than you expect, unless you already have the necessary kprobe written and tested
tfheen: 2006-06-29, status implemented. The kprobe is available at http://people.ubuntu.com/~tfheen/bzr/tally_open/ and I am giving the file list to Adam so he can use it when building the squashfs images.
