Raphaël Enrici has proposed merging ~yadle/cloud-init:fix-ipv6-configuration
into cloud-init:master.
Commit message:
Nocloud v1 config passes static6 as the type of subnet. This patch replaces
static6 by static during interfaces file generation as static6 is not a valid
keyword in /etc/network/interfaces
Requested reviews:
cloud-init commiters (cloud-init-dev)

nocloud v1 network-config looks like this:
version: 1
config:
- type: physical
name: eth0
mac_address: b2:b8:6e:6f:58:47
subnets:
- type: static
address: <ipv4 addr>
netmask: 255.255.255.224
gateway: <ipv4 gw addr>
- type: static6
address: <ipv6 addr>
gateway: <ipv6 gw addr>
...
Without the patch this leads to that kind of file:
/etc/network/interfaces.d/50-cloud-init.cfg:
<snip>
auto eth0
iface eth0 inet static
address <ipv4 addr>
gateway <ipv4 gw addr>
# control-alias eth0
iface eth0 inet6 static6
address <ipv6 addr>
gateway <ipv6 gw addr>
<snip>
Which is not valid, at least in ubuntu xenial. With the patch we get the right
entry for ipv6 configuration:
# control-alias eth0
iface eth0 inet6 static <<<---- 6 removed here
address <ipv6 addr>
gateway <ipv6 gw addr>
