Providing default root password /etc/shadow

Hi, I am new to lede and trying to use openwrt for a fun project. The target board is rpi-b+ and it works as expected. However, there is no default password on the openwrt and have to set it up after booting the device. I know lede has the /etc/passwd and /etc/shadow file in the base-files package. It would be great if someone can suggest me the way to update these two file to provide a default root password built into the firmware. Thanks in advance, Naz.
