Indeed. I use skopeo extensively, so I do like it. But I'm still holding out hopes that something else will come out of the CNCF/OCI working groups that is smaller, or at least a better defined and focused. When someone asked this before, the tooling really isn't the hard part. It is going to be licensing, reproducibility, support, etc, etc. So if we were able to do this, there's many landmines that aren't technical. > Sure, it comes with some extra features, and if there is a more > lightweight solution that would be nice.

All of the different disk support was spidering through a lot of utilities that weren't easy to build as -native. But absolutely, the go packaging is better now, and we have just captured / fetched what we need in most of the recipes, so there's no longer 30 or 40 go recipes to extend to native (and of which 20 broke when I tried it).
