The netconsole service is responsible for loading the
netconsole kernel module, which logs kernel printk messages over UDP to a
syslog server. This allows debugging of problems where disk logging fails and
serial consoles are impractical.
The netconsole service can be disabled with the following command:
$ sudo systemctl mask --now netconsole.service
The netconsole service is not necessary unless there is a need to debug kernel panics, which is not common.
