IMHO disabling an old and trusted functionality is simply introducing a bug, made worse by keeping silent about it (no word about it in changelog.gz or NEWS.Debian.gz). It must surely be a tiny minority of users who press control-alt-backspace "by mistake"; I find it hard to imagine even. But for users who suffer from this syndrome there has always been the possibility of specifying DontZap. Forcing it on all users is a Bad Thing. Regards, Jan
