The containerd-shim creates pipes and passes them to the init container as stdin, stdout, and stderr for logging purposes. By default, these pipes are owned by the root user (UID/GID: 0/0). The init container can access them directly through inheritance. However, if the init container attempts to open any files pointing to these pipes (e.g., /proc/1/fd/2, /dev/stderr), it will encounter a permission issue since it is not the owner. To avoid this, we need to align the ownership of the pipes with the init process. Fixes: #10598 Signed-off-by: Wei Fu <fuweid89@gmail.com>
