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.
