Small live images
For whom may need, I have written a script to build small image (faster
to load). see
Feel free to implement it within live-helper (or simplify the script if
I missed some features of Live Helper)
BTW, the patch "Removing the whole cache, not just the .deb cache.."
doesn't work : i think the /var/cache/apt/pkgcache.bin is rebuilt later
(during deconfigure stage).
