# null may already exist; therefore ownership has to be changed with command

I am not sure this is true.

                        if (!delete && major >= 0) {
                                if (mknod(node_name, mode | type, makedev(major, minor)) && errno != EEXIST)
                                        bb_perror_msg("can't create %s", node_name);
                                if (major == root_major && minor == root_minor)
                                        symlink(node_name, "root");
                                if (ENABLE_FEATURE_MDEV_CONF) {
                                        chmod(node_name, mode);
                                        chown(node_name, ugid.uid, ugid.gid);
                                }
                                if (ENABLE_FEATURE_MDEV_RENAME && alias) {
                                        if (aliaslink == '>')
                                                symlink(node_name, device_name);
                                }
                        }

The code above does not skip chown() if the node exists,
it still would do that.

random          root:root 666
urandom         root:root 444
hwrandom        root:root 660

random and urandom modes seem out of sync.
