问题
I am building an image with Yocto/Poky release Daisy 1.6.3.
What is the correct way or config file where to set the root password? The default password is empty and I can't find a place where to specify it.
回答1:
Here is what you have to do in your recipe.
inherit extrausers EXTRA_USERS_PARAMS = "usermod -P p@ssw0rd root;"
where p@ssw0rd is the password you want root user to have.
This link may help you.
As "debug-tweaks"'s goal is to set root's password empty, you must remove it from your EXTRA_IMAGE_FEATURES.

As of Poky 2.1.2; to set the root password the following instructions need to be added to local.conf:
INHERIT += "extrausers"
EXTRA_USERS_PARAMS = "usermod -P p@ssw0rd root;"
No need to remove debug-tweaks

Here is method I used which does not use the -P switch on the usermod command. You must use the following form:
EXTRA_USERS_PARAMS = "usermod -p $(openssl passwd p@ssw0rd) root;"
The usermod -P command does not work in my version of linux.
See How do i change the root password in the Yocto dora bitbake system?

Add the below linw at your conf/local.conf file
INHERIT += "extrausers"
EXTRA_USERS_PARAMS = "usermod -P urpassword root;"
