Hi everyone,

I conduct the experiment according to the following article(https://d7y.io/zh/docs/setup/integration/nydus). And an error occurred when I reached this step:
nerdctl --snapshotter nydus run --rm -it $DOCKERHUB_REPO_NAME/python:3.9.15-nydus
Error msg:
FATA[0005] mount callback failed on /run/user/0/containerd-mount3572667506: read /run/user/0/containerd-mount3572667506/etc/group: input/output error

Does anyone know how to solve this problem?

[ENV]
os: centos 7.3, kernel-4.18
nerdctl version 1.4.0
containerd version: Version: v1.7.1
docker version: 18.06.3-ce

Is this specific to Nydus?

Hi AkihiroSuda,

Is it a containerd's defect? From containerd source code, it's seemed that failed at func WithTempMount. And the default tempDir is set via env XDG_RUNTIME_DIR(default is /run/user/0). Is there any work around to skip that issue?

By the way, I checked this issue #690. Is it the same issue?

Thanks
