can the rust cp impl. be built for all target platforms supported by go? What I have in mind are ibm z + power (that's what we have to support).

yes, s390x and ppc64le are supported by the rust base image and musl.
Are you using the autoinstrumentation images that are published from this repo in those platforms? I'm asking because today they only support arm and x86 (please take a look here)

Issue: #1600
Apologies for this taking so long. As mentioned in the issue we would like to propose a replacement to the busybox base image used in the auto-instrumentation images. This PR is a demonstration on what that implementation would look like for a single auto-instrumentation images. If this proposal is accepted followup PRs would be made to adjust the remaining dockerfiles and github workflows.
The Rust based CP tool is statically linked to MUSL, which is licensed under MIT license. This implementation handles all the cases currently required by the Operator auto-instrumentation images: regular file copy (used in the Java) and archive copy (used in Python and NodeJS).
This is currently in use in our ADOT Java Instrumentation agent. Dockerfile ref.
Please feel free to ask any follow up questions. I will ensure this is brought up in the next sig meeting.
