Well, looks like you're right. In which case, it's a Fedora "feature".
I'll pick another distro for liveUSB support next time I need to install

Good luck with your application to GT. And if you decide to go here,
make sure to check the age of the residence halls before signing up.
Some of them haven't been renovated in a long time.
