Summary
The user is building Yocto Linux within a container and is encountering an issue with SSH git support while following best practices against compiling as root. They have created a user named builder to perform the build process. However, the forwarded SSH authentication socket is owned by root, preventing the builder user from accessing it. While a standard Dockerfile allows for a workaround using RUN --mount=type=ssh,uid=<uid of builder>, this option is not available in Earthfile. The user is seeking a solution to this problem.

Hi, A while back I was asking questions surrounding SSH git support.
I've now found another scenario which is tricky to get right with Earthly.
I'm attempting to build Yocto Linux from within a container. Yocto explicitly wants you to not compile as root. So the dockerfile (Earthfile) sets up a user called builder that does the actual building.
One of the steps of the build process is to fetch source code from a number of git repos using SSH. I use RUN --ssh of course but what happens is that the forwarded auth sock /run/buildkit/ssh_agent.0is owned by rootand cannot be accessed by builder. In Dockerfile using RUN --mount=type=ssh,uid=<uid of builder>would do the trick, but doesn't seem to be supported by Earthfile.
Is there a way to get around this?
