So everything in Rawhide must be compiled with -fPIC?

I don't necessarily disagree, I don't believe we should be holding the
distro back for the device but at the same time it's a good example of
a widely deployed device running Fedora.

You are correct as can be seen from the release notes [1] but then it
was in development from mid last year when F-20 was "stable" and there
are Community releases [2] that support all of the devices. There are
also people using and testing F-21 and even F-22.

Actually it wasn't very divergent from mainline Fedora at all.
Primarily kernel and sugar specifics actually, I was on the OS dev
team :-)

It was used as an example of supported hardware that should be
considered in the impact of the changes we make. I can use a eeePC
netbook, a beagle bone black or any number of other low powered
devices if it would make you more comfortable. You as one of the
Fedora kernel people know the old hardwarw that people use.

The point that I was making was not that we should stop change for the
tailing end of the hardware that we currently support but to be aware
of the impact of the changes that are made and that not every use can
afford to have a nice shiny core i7 Asus/Lenovo/Mac device sitting on
their desk. You could probably use some crappy bottom of the line
cloud instance with 256Mb of RAM, shared CPU and dreadful disk IO as a
decent bottom end baseline actually, and yes I'm aware you wouldn't be
running the desktop apps we're discussing here on said platform.

I wouldn't as we don't currently support them as their kernel isn't
currently upstream, but substitute a beaglebone black, I'll happily
send both....  you can substitute any number of low end devices and my
point still remains the same!
