since the Beaglebone Black is currently difficult to purchase
I'm looking for alternatives.
Where are you trying to buy it from? I've not ever had issues and I've
seen people receiving them recently.
What is the status of Fedora on the Cubieboard?
I saw that announcement
http://cubieboard.org/2014/01/13/fedora-20-available-for-cubietruck/
But one comment says, that it stopped working after an "yum update".
Any news on that?
That was always a remix, personally I have no idea who did that.
We're planning on supporting AllWinner devices officially upstream in
mainline when Fedora 21 in released in October. The other devices you
may want to look at are the WandBoard devices. Others have reported
luck with the CuBox-1 devices
