Optimized Live CD layout for faster boot

Registered by Krzysztof Lichota on 2006-06-08

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.
