- for the meeting today (top down):
- overview of the CoreOS Layering technology
- https://github.com/coreos/coreos-layering-examples/
- organization around defining use cases
- develop subgroup for use case definition
- what use cases are in scope, what are out of scope?
- how does it fit in our story with Ignition?

- bottom up
- Figuring out the updates strategy
- containers pull from a tag - linear update model
- we need to figure out how to get zincati/cincinnati integrated in this process
- might need another piece of software to consume the update graph and build all needed layered containers to allow for updates to happen for nodes following this particular container in a registry
- releng
- figure out container pushing to the registry
- consider multi-arch
- maintaining ostree and container registry
- do we need tooling for allowing users to build their own bootimages?
