Is "netplan apply" required if I reboot after changing /etc/netplan/xxx-config.yaml file

Question

If I change the network device config in /etc/netplan/00-installer-config.yaml and then reboot will it apply the changes, or must I explicitly do "netplan apply"?

(Ubuntu 22.04)

Answer 1

According to the documentation it is not necessary to run netplan apply manually after a reboot:

During early boot, the netplan “network renderer” runs which reads /{lib,etc,run}/netplan/*.yaml and writes configuration to /run to hand off control of devices to the specified networking daemon.
