[MapProxy] mapproxy and S3

Hi all,

I am using Mapproxy 1.12.0a with a fully seeded tile cache stored on Amazon
S3. I'm running Mapproxy on EC2 instances which are using an IAM role.

I have a cache directive as follows:

    format: image/png
    request_format: image/png
    grids: [ "EPSG:3857" ]
    sources: []
    minimize_meta_requests: true
      type: s3
      directory: TileCache3857/Carto/
      bucket_name: cache
      directory_layout: arcgis

I have a few questions:

1. How do I attach an on_error section (as seen in a source usually) to
this? I don't have a source, but if someone zooms in too far I'd like to
set the colour etc..

2. How do I switch IAM role - I'm using cross-account S3 so I can't assign
the correct role on instance start.

Thanks for the help,
