When booting under systemd, you can disable cloud-init completely by either:
- creating a file:
sudo touch /etc/cloud/cloud-init.disabled - or adding
cloud-init=disabledto the kernel command line as found in/proc/cmdline
To partially disable some functions, modify: /etc/cloud/cloud.cfg, for example to disable network configuration:
sudo su -
echo "network: {config: disabled}" > /etc/cloud/cloud.cfg.d/99-disable-network-config.cfgsudo nano /etc/default/grub config
GRUB_TERMINAL="console serial"
sudo update-grub
