Steps to reproduce the problem:
1. Switch to developer mode
2. Set root password
3. Ensure that you can't get root access with sudo/su

What is the expected behavior?
sudo and su should accept root password

What went wrong?
After powerwash I set root password then open terminal to get root access, but sudo and su don't accept my password. I found workaround: I connect to my Chromebook via ssh with username root and root password, then I do "passwd chronos" to set the same password. It helps to get root access locally. But each update ChromeOS resets my password and switch ssh access off. It forces me to powerwash my Chromebook again.

Did this work before? N/A
