Note the "emerge -e world" is not what we need here as it will leave broken system packages (the system won't boot on the new processor). The '-e' option looks for the USE flags only. We are supposed to know what we do with Gentoo. Having hardware specific options makes the distribution in a possibly jail. Nevertheless, Gentoo and Linux offer all generic options to ensure x86 processor-like migrations. -- Nicolas Sebrecht
