If you didn't use DHCP settings as your new static address, the Pi will restart after this dialog.  If you are using SSH, you may need to reconnect using the IP address above.

The install log is in /etc/pihole." $r $c

# If a custom address was set, restart
if [[ "$rebootNeeded" = true ]];then
	# Restart to apply the new static IP address
	sudo reboot
else
	# If not, just start the services since the address will stay the same
	sudo service dnsmasq start
	sudo service lighttpd start
