Plus, even if not malicious, this script messes with a bunch of system config: * installed unattended-upgrades (from a random github repo instead of apt repos * passes --yes to apt-get, which may remove important packages * reconfigures /sbin/iptables to link to /usr/sbin/iptables-legacy * saves the current iptables rules (some of which may have been set temporarily by root) * overwrites existing dhcpd config if it already exists * overwrites existing openvpn-related config if it already exists (including syslog)
