Currently, a config like this:
| version: 1
| config:
| - 'type': 'physical'
| 'name': 'iface0'
| 'subnets':
| - {'type': 'dhcp4'}
| - {'type': 'dhcp6'}
Will render:
| auto lo
| iface lo inet loopback
|
| auto iface0
| iface iface0 inet dhcp
| post-up ifup iface0:1
|
|
| auto iface0:1
| iface iface0:1 inet6 dhcp
Below is an example test case that shows the output.
Heres the problem:

=== Begin SRU Template ===
[Impact]
cloud-init rendered ENI (/etc/network/interfaces) configuration using
"aliases" (eth0:1). That fails in some scenarios to bring up all interfaces
on boot.
Most specifically problematic is dhcp with ipv4 and dhcp with ipv6.
In that case ipv6 dhcp just would not come up on boot.
[Test Case]
There are unit tests to verify that the new network configuration
is written as expected. Additionally, this is now using the same
ENI rendering format that curtin uses, which has good test cases
in its 'vmtest'.
[Regression Potential]
Users who had done:
ifup eth0:1
will no longer be able to do that. However now this will reliably work:
ifup eth0
to bring up all ip addresses on eth0.
=== End SRU Template ===
Currently, a config like this:
| version: 1
| config:
| - 'type': 'physical'
| 'name': 'iface0'
| 'subnets':
| - {'type': 'dhcp4'}
| - {'type': 'dhcp6'}
Will render:
| auto lo
| iface lo inet loopback
|
| auto iface0
| iface iface0 inet dhcp
| post-up ifup iface0:1
|
|
| auto iface0:1
| iface iface0:1 inet6 dhcp
Below is an example test case that shows the output.
Heres the problem:
$ sudo sh -c 'ifdown eth0; ifup eth0'
