Running a nonproduct flavor (in my case KDE spin) of Fedora 21 fedup fails with the above mentioned error. Here's the complete error message of the upgrade command suggested by http://fedoraproject.org/wiki/FedUp#How_Can_I_Upgrade_My_System_with_FedUp.3F :

sudo fedup --network 22 --product=nonproduct
usage: fedup <SOURCE> [options]
fedup: error: unrecognized arguments: --product=nonproduct


The same holds for the command suggested by 'man fedup':

sudo fedup --network 22 --product nonproduct
usage: fedup <SOURCE> [options]
fedup: error: unrecognized arguments: --product nonproduct

BTW, which one is the correct one?


Version-Release number of selected component (if applicable):
fedup-0.9.2-1.fc21.noarch

How reproducible:
Every time.
