Q: How do I set / change the root password?
A: Use the extrausers class to set the password. In your image recipe:
inherit extrausers EXTRA_USERS_PARAMS = "usermod -p '\$5\$sIhB3FmJb4oSx.uN\$WWE8AJP8ybR03TXBJ2JMZJ6LpsrvcwKmsHxxY.asDR6' root;"
This sets the root password to a hashed value of "1876*18". If you prefer to do this in local.conf or your distro configuration, you'll need to change the first line to INHERIT += "extrausers".
To obtain the hashed value for a password, you can use the following command:
$ python -c 'import crypt; print(crypt.crypt("1876*18", crypt.METHOD_SHA256))'
| WARNING: if you are hardcoding a root password for a production image deployed to multiple devices, consider carefully the ramifications of doing so before proceeding. |
Note some characters may need some level of escaping to make it correctly into /etc/shadow (examples shown should work)
Q: How do I add users?
A: Use the extrausers class to and the user and set the password. In your image recipe:
inherit extrausers EXTRA_USERS_PARAMS = "useradd -p '\$5\$vn9du4U3jghFZaqC\$Fl6pQZK5FUoT2D6Twij3OpjGR9FXFsE1r/vyMtGooX6' myUser;"
This adds the user myUser and sets the password to a hashed value of "2015*08". As above, if you prefer to do this in local.conf or your distro configuration, you'll need to change the first line to INHERIT += "extrausers".
