Underdog: Unleash the Power

[Pelo]

sfs load on the fly : i am used to load 'old puppies' on the fly of newest one. It is based on underdog processus, in my opinion.
But i unload them before shutdown, frightened to break anything
With Puppy, rather than thinking about what should work or not, i decided to do it
with 4gb ram, it's easy, and it works perfectly.
