"Permission Denied Error when Running Non-Root Podman Development Container: mkdir: cannot create directory ‘/root’"

[mimowen]

I find an issue with the VSCode Dev Container template image trying to create files in the /root directory within the container using the vscode username. Here's the error I received:

[16535 ms] Exit code 1
[16535 ms] Start: Run in container: test -d '/vscode/vscode-server/bin/linux-x64/ea1445cc7016315d0f5728f8e8b12a45dc0a7286'

The /root directory has default permissions set to 700 in Ubuntu 22.04.4 LTS, which caused this error.

After modifying the /root directory permissions, I found that the Dev Container extension is able to create the /root/.vscode-server directory within the container. Everything works fine now, and I can happily use the Dev Container extension.

So I want to know why this happened ？what caused this？
