cloudinit/net: handle two different routes for the same ip (#1124)
If we set a dhcp server side like this:
$ cat /var/tmp/cloud-init/cloud-init-dhcp-f0rie5tm/dhcp.leases
lease {
...
option classless-static-routes 31.169.254.169.254 0.0.0.0,31.169.254.169.254
10.112.143.127,22.10.112.140 0.0.0.0,0 10.112.140.1;
...
}
cloud-init fails to configure the routes via 'ip route add' because to there are
two different routes for 169.254.169.254:
$ ip -4 route add 192.168.1.1/32 via 0.0.0.0 dev eth0
$ ip -4 route add 192.168.1.1/32 via 10.112.140.248 dev eth0
But NetworkManager can handle such scenario successfully as it uses "ip route append".
So change cloud-init to also use "ip route append" to fix the issue:
$ ip -4 route append 192.168.1.1/32 via 0.0.0.0 dev eth0
$ ip -4 route append 192.168.1.1/32 via 10.112.140.248 dev eth0
