I suspect downgrading from non-hardened to hardened will be impossible; glibc-2.6.1 is stable on x86 at least, so in all probability almost all x86 boxen will at least have that. But >=glibc-2.6 is hard masked on x86 so there is no commonality and no version available where the glibc ebuild will even permit this required downgrade. It would seem that a reinstall is the only possible way to do this. -- alan dot mckinnon at gmail dot com
