Yes, but still, both emerges may run while you work, so that's not wasted time, while on a new install, your machine is useless till you get all that you need running (that's the compilation time for X, an office suite, a window manager), and after that, you gotta transfer all your files and settings (that may be tedious), and all of this takes a time you could use to work... All I'm saying is that you really don't need to start from scratch, I personally find it more productive and fast (not to mention less boring) to prepare and transfer the whole install, and only configure the new hardware (that is part of a normal new install, so, you can't avoid that), instead of waiting for compilations to end so you can use packages on your new machine. Besides, I'm letting the official portage tool do its job... Anyway, it is MHO. In some cases, this may fail and a install from scratch is the only option left. But I never had this bad luck. -- Daniel da Veiga
