          I also see this inside of a nix-shell, where `TMP` and `TMPDIR` is set to a dedicated temp directory from `/tmp/nix-shell.XXXXXX`.

Can you provide more detailed instructions for reproducing this? I'd need the exact command line.

I have been trying to reproduce with:

TMPDIR=/home/oquenchil/tmpdir USE_BAZEL_VERSION=7.1.0 bazelisk build --action_env=TMPDIR=/home/oquenchil/tmpdir --sandbox_debug :foo

I think you need to set TMPDIR to a directory inside /tmp to trigger the error. Since /tmp is mounted empty inside the sandbox, the given TMPDIR does not exist...

It works for me, when I use --noincompatible_sandbox_hermetic_tmp.

\edit: Oh, I came here from #5900. I don't see the permission denied error, but No such file or directory.
