There was a problem hiding this comment.
Or, like Ignition should we default to failing when there is an extant file there? That gets annoying though because suddenly one needs an extra override flag for when it's truly necessary.

That said...hmm. Maybe even without a registry, we should really still track this filesystem state in a somewhat more rigorous way by keeping each individual provided path as an extra hidden layer (ostree commit/ref), something like And now that we effectively have 3 sources for
We can diff all three of these. How exactly we make this visible gets tricky...and does still beg the question of supporting more useful metadata for them, and remote fetches. |

One technical difference here I am seeing vs systemd confext is that we definitely need to support configuring systemd units via this mechanism. |

FWIW, I rebased this and cleaned it up a bit. I'm still not totally sure about it though. |
This allows injection of arbitrary config files from an external source into the target root. This is pretty low tech...I'd really like to also support structured, cleanly "day 2" updatable configmaps, etc. But there is simply no getting away from the generally wanting the ability to inject arbitrary machine-local external state today. It's the lowest common denominitator that applies across many use cases. We're agnostic to *how* the data is provided; that could be fetched from cloud instance metadata, the hypervisor, a USB stick, config state provided for bootc-image-builder, etc. Just one technical implementation point, we do handle SELinux labeling here in a consistent way at least.
