I tried this out on a build that I am working on for which I needed to add a root password and to create a non-root user with a password. If I use: EXTRA_USERS_PARAMS += "usermod -p `openssl passwd -6 ${ROOT_PASSWORD}` root;” When I try to login to the device it rejects the password that was defined as ROOT_PASSWORD. If I remove the “-6” from the openssl command and rebuild/deploy the image then I can login to the target as expected. Is there something else that needs to be defined/included in the Yocto configuration in order for the “-6” option to work? -Andy.
Sorry, I forgot to mention that with password algorithms like the -6 we need the two ' ' around the openssl command, because the generated hash contains the "$" character, that is resolved as a bash variable somewhere in the process.
But at this point I'm not sure if ${ROOT_PASSWORD} works (I'm using the password wrote on the command, not passed by variable).
