[Openstack] Metadata and File Injection (code summit session?)

Except for the fact that the config drive is non-EC2 right?

That might blow it out of the water to start, as I know a lot of people want the EC2 equivalents/compat.

But maybe if done right it shouldn't matter (ie cloud-init could instead of calling out to urls could also call out to "local files" on a config drive).

I just worry that config drive is openstack api only, afaik.

I think config drive is "injection done right"; it doesn't need to figure out a partition because it creates its own.

Config drive + the init script I've contributed is rock-solid for me.  No metadata service to go slow or need special configuration, no DHCP problems etc.

If there's a proliferation of options, we should identify the important use cases and make sure that we have a good approach for each of them.  Config drive is very under-utilized, in my opinion.

I was looking at this area earlier in terms of how the system works out what partition to inject keys/files/etc into, which feels like it should be specified by image metadata but currently defaults to partition 1.

Made me wonder if we really need so many different ways for instances to get their metadata ?
