Speaking of debugging, does including the debugging symbols affect run-time operation? I would not think so but on old hardware might that be true? I wonder because now in hindsight I remember I never built or installed the debugging symbols for the 3.5.10 or TDE 3.5.x packages. (I'm still not letting newer versions of X and the kernel off the hook. Just wondering out loud.) Darrell
