Comment 0 for bug 1805854

With the announcement of EC2s A1 instances we'd (CPC) like to be able to rely on cloud-init to configure archive mirrors for non-x86 architectures.

Currently the AMIs have the mirrors configured using /etc/cloud/cloud.cfg.d/95_mirrors.cfg which points to the in region archive mirrors for non-x86 architectures.

```
# Add archive mirrors for non-x86 architectures
system_info:
   package_mirrors:
     - arches: [i386, amd64]
       failsafe:

```

See http://paste.ubuntu.com/p/QGvGKpKYKb/ for current AMIs that can be used for testing.

Please let me know if you would like me to spin up instances for testing instead or if you need any further info.
