This is why if anyone is opposed to running SELinux it should be left in permissive mode. Brandon Vincent ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Even in permissive mode you still incur the system overhead cost (7% performance hit, last I read) and the excessive logging. And don't even get me started about having /tmp mounted on a tmpfs filesystem! :-) There are good reasons to prefer disabled over permissive if you've sure you won't need to re-enable SELinux later. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
