Title: Disable SELinux and requiretty

With SELinux in Enforcing state, "useradd -g stack -s /bin/bash -d $DEST -m stack " will report error "Permission Denied to mkdir $DEST";

With "Default requiretty " enabled in /etc/sudoers , script reports "sudo: sorry, you must have a tty to run sudo". And this is enabled in fedora by default.
