Previously, at manual system installation time, the OS installer would prompt you for a root password. Now, in addition to that, it will prompt you for the name/password of a user account intended to be the day-to-day account of the sysadmin.

If you follow along with this path, you will find out to your chagrin that you can no longer log in as root!

Attempts to log in as user root will be met with the complaint "Roles cannot log in directly". Instead, to run commands as root, you will be expected to use either sudo (with your own password) or su (with the root password).

If you find yourself in this situation and it does not sit well with you, don't panic! You can restore root to its full account status by editing the file /etc/user_attr and setting root's entry to be type=normal rather than type=role.
