MAAS should not add 'source /etc/network/interfaces.d/*.cfg' to /etc/network/interfaces

[Andrew McDermott]

Looking at a deployed node I have:

ubuntu@maas19-node1:~$ more /etc/network/interfaces-before-add-juju-bridge
auto lo
iface lo inet loopback
    dns-nameservers 10.11.19.2
    dns-search maas19

auto eth0
iface eth0 inet static
    gateway 10.11.19.1
    address 10.11.19.110/24
    mtu 1500

auto eth1
iface eth1 inet static
    address 10.11.19.111/24
    mtu 1500

auto eth2
iface eth2 inet static
    address 10.11.19.113/24
    mtu 1500

auto eth3
iface eth3 inet static
    address 10.11.19.112/24
    mtu 1500

source /etc/network/interfaces.d/*.cfg

and ALSO:

ubuntu@maas19-node1:~$ tree -a /etc/network/interfaces.d/
/etc/network/interfaces.d/
`-- eth0.cfg

0 directories, 1 file

ubuntu@maas19-node1:~$ cat /etc/network/interfaces.d/eth0.cfg
# The primary network interface
auto eth0
iface eth0 inet dhcp

So when the machine boots I start off with a static IP address then get a DHCP address.

This is relatively new behaviour as for a long time the /e/n/i I would get from a MAAS deployed node would not get the 'source' stanza.

This is MAAS 1.9.3:

aim@maas19:~$ dpkg -l |grep maas

Hi Andrew,

Can you please attach the version of curtin you are using ? This is an issue in curtin.
