What operating system are you running Bazel on?
Linux
What's the output of bazel info release?
Custom build on top of 3.7
Have you found anything relevant by searching the web?
Any other information, logs, or outputs that you want to share?
I assume this warning is benign - in the sense the build still proceeds, although some additional actions need to be executed.
- Are there plans to support symlinks for remote download minimal, or is this intrinsic issue with builds without bytes?
