Introduction
By default on buildroot there is no password for root user. It is not really secure and can be a problem for some packages like dropbear. This page explain how to set a default password on our board.
On target
The straitforward way to set the root password is to login on the board then type :
# passwd Changing password for root New password: Bad password: too short Retype password: Password for root changed by root
If your password seems to be too simple for the system it will tell it, but the password is changed.
On host
If we have a big production of APF* to flash with the same default password it will be really painfull to change it on each boards. The best way is then to change it under our rootfs.
