digital ocean: enp0s3 -> ens3

 I hit a few subtle problems along the way:
 * DO doesn't do dhcp so we have to hard-code the network configuration
-* Ubuntu still uses eth0, 1 etc, not enp0s3 etc so we have a network
+* Ubuntu still uses eth0, 1 etc, not ens3 etc so we have a network
   link name change after the reboot.
 * I had to modify nixos-infect to reflect the network link name changes,
   and to not reboot to avoid ssh-interruption and therefore errors.
