Custom glibc: Patchelf permission denied

[Morgensol]

Type: Bug

1. Set the remoteUser to a non root user or have the default user set to a non root user
2. Follow the offical guide on building and patching the vscode server https://github.com/microsoft/vscode-docs/blob/main/docs/remote/faq.md#can-i-run-vs-code-server-on-older-linux-distributions
3. This makes the patching fail due to the following error: "patchelf: open: Permission denied"

I believe this issue is comming from the fact that the vscode volume is the one being directly patched instead of the linked one in the home folder. The /vscode folder is being owned by root and unless run as sudo it cannot be patched.

I have tested that changing the user to root makes it work. I have tried multiple ways of chown'ing on the /vscode folder in the remote ("postcreate" etc) but i have not been successful with it.

I have done some more digging and it seems to me the issue is actually because when installing the vscode server on the dev container it runs the container in a root context:
[2025-11-03T10:02:28.730Z] Start: Run in Host: docker exec -i -u root container id /bin/sh
