Hi @nikola-jokic This is what we were talking about last week when we met, is this something that you can take a look at? Thanks! |

Thanks, moved |
Currently, the permissions of /home/runner are 750. In some container runtimes and Kubernetes distributions (including OpenShift), a different uid/gid (not `runner`) may be used when running the image. The runner expects to be able to read and execute scripts within the home directory, and it will also write ephemeral files, diagnostic data, etc. into the directory as well. Therefore, to support the ability to use the runner as a user apart from `runner`, full 777 permissions are needed. A longer-term change to consider which may improve the security posture here would be to separate the executable portions of the application (scripts, etc.) from the places where temporary data is written, and control the permissions of these separately.

True @caxu-rh, my bad, I tested it partially, but it is still better at least from my point of view to have |

| WORKDIR /home/runner | ||

@TingluoHuang @nikola-jokic This is a breaking change after upgrading the GitHub runner from 2.329.0 to 2.330.0. We are now seeing the error “failed to initialize build cache.” We need to revert back to 2.329.0. Could you please fix this so we don’t need separate handling on our side?.

@nikola-jokic - one difference I'm seeing is in the owner uid/gid of the /home/runner directory.
- In 2.329.0:
Access: (0750/drwxr-x---) Uid: ( 1001/ runner) Gid: ( 1001/ runner) - In 2.330.0:
Access: (0777/drwxrwxrwx) Uid: ( 0/ root) Gid: ( 0/ root)
I think the ownership change is due to moving WORKDIR above. I don't quite understand how this ownership change is causing the observed behavior, though.
