Public bug reported:

Using MAAS 2.2.2 and newest CentOS image that uses cloud-init cloud-
init-0.7.9+224.g681baff-1.el7.centos.noarch, network configuration is
being create even when configuration already exists.

MAAS deployed an image that configures network interface via custom
curthooks on the image. However, cloud-init also creates network
configuration:


[centos@withkvm ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0 
# Created by cloud-init on instance boot automatically, do not edit.
#
BOOTPROTO=dhcp
DEVICE=eth0
HWADDR=52:54:00:03:02:6e
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
USERCTL=no

## Configuration created by custom curtin hook/config
[centos@withkvm ~]$ cat /etc/sysconfig/network-scripts/ifcfg-ens3 
TYPE="Ethernet"
NM_CONTROLLED="no"
USERCTL="yes"
HWADDR="52:54:00:03:02:6E"
ONBOOT="yes"
BOOTPROTO="dhcp"
PEERDNS="yes"
PERSISTENT_DHCLIENT="1"
