Using anaconda 20.21, I noticed when I entered my usual testing root password (111111) that the little yellow informational bar was missing the reason why it was bad. It just said (paraphrase) "The chosen password is weak: . Press Done again to continue anyway." - probably forgot the exact wording, but the point is, obviously where the reason for the weakness should be substituted in, it hadn't been, and there was just a hanging space.
This was on a live CD I built to do a test run ahead of F20 beta TC1 - live image is all packages from current f20 'stable', I yum update'd anaconda and pykickstart from updates-testing before starting the install.
