Description

Is it possible to configure the defaults to put debug logging etc. in a different directory from the GitHub workspace?

I end up with a buildkitd.toml and buildkitd.log if I do a Docker build with these files not .dockerignored and do a top level COPY ./ ./. While this is easy to not do,

Expected behaviour

No buildkit config / log files in a built image.

Actual behaviour

buildkitd.log and buildkitd.toml are present.
