It has come to our attention that the Pidora name bears an unfortunate similarity to another word in Russian, and this has offended some community members and amused others.
Please accept our apologies for any offence caused. Our goal was to simply associate "Pi" (from Raspberry Pi) and "Fedora" (from the Fedora Project).
We are actively seeking a broadly-acceptable alternative Russian name in consultation with some community members, and will post more information shortly.
