At the moment there is no current Fedora releases available for the Raspberry Pi. pidora doesn’t seems to switch to Fedora 20 soon. That’s bad, but actually I don’t care what kind of Linux I’m using as long as they have a similar tool set (thinking about systemd).
So, I decided to go with Arch Linux. The setup is not different to other distros. But it will definitely need some time to adjust to the package management system 😉
