Has this tutorial worked for anyone? The 1st error is saw was under Move files to temp filesystem after running:

touch /tmp/dhcpcd.resolv.conf; ln -s /tmp/dhcpcd.resolv.conf /etc/resolv.conf

Failed to create symbolic link ‘etc/resolv.conf’ file exists. Next after reboot see errors regarding “a start job is running for dhcpd on all interfaces..." The raspi fails to boot and see pi@raspberrypi: prompt. Thanks in advance for any insights!
