This is failing openQA tests because it's broken something we do in some of those tests. We need the root account to have a password on the install system for the post-install tests to work. The Workstation live installer does not let you set a password for the root account during install, so after the install is complete - but with the installer still running - we go to a console and run "echo 'root:weakpassword' | chpasswd -R /mnt/sysimage" . This should set the root password in the installed system to "weakpassword", and has worked for years. But with this update it fails, saying:

chpasswd: (user root) pam_chauthtok() failed, error:
Authentication token manipulation error
chpasswd: (line 1, user root) password not changed

That obviously breaks the test, because on reboot, it can't log in as root as it expects to. This does seem like a bug.
