only live usb,specialized ops
having last version binaries ready + some dependencies is a huge time saver, the idea to use ubuntu repo is good, but we all know those debs are full of useless stuffs and you can't never find an application with right dependencies, or depends are too many (or too less...
relying fully on those debs+deps, at the end there isn't much added value... +or- as lubuntu
so I made up my own strategy.
Basically, cutting away some of those deps, plus keeping track myself of already installed debs, plus further clean the resulting sce, I'm reducing dimensions half, and more.
luckily sce structure is very smart, it keeps inside the debs list used, so, at next ubuntu release it will be much simpler: just provide the same list to sce-import
