If the compilation will fail at a certain point (and it will fail, since this is a complete new thing) -- would it be possible to resume even some tweaks, hacks and patches (even certain recompilations) would be needed in between? Can I stop a running emerge @world and resume later? How does a restarted emerge @world recognizes packages, which are already compiled according to the new standard? Cheers Meino
