When running bazel build with --experimental_guard_against_concurrent_changes warnings are produced about concurrent modification and as a result not uploading the results to the cache.

Might be related to https://github.com/bazel-contrib/rules_oci/blob/main/oci/private/pull.bzl#L224 or something similar

Its hard to tell what might be causing this, and this is probably really hard to reproduce. For what it is worth, this check would run after oci_pull has completed running, my best guess is hardlinks are making your build sad

rules_oci/oci/private/pull.bzl

Line 172 in a911e9e

hardlink = "on",

.

Can you try manually patching this line and try to see if works?
