This seems wildly at odds with

1) what the people using Power in production are targeting (not desktop at
all)

2) what the enthusiast people for ARM are building. After all, the
annoucement explicitly says "The image is available for each of the major
desktop environments" (which, not true), and people in this very thread are
suggesting interested developers get Chromebooks.

I mean, I do know what some people want ARM to be in terms of dense
hypserscale servers (32/64-bit)... but the community that would be using
Fedora ARM does seem to be targeting a wider array than that.

So, in terms of PA, I think there are reasonable guides of parity that need
to be met:

- If a feature claims to be supported on both arches, it should work the same.

Hence, stack-protector needs fixed.

- The main interface for documented Fedora workflows should be the same.

Hence, use of Anaconda, use of systemd, etc.

- The core functionality should work the same

Kernel, glibc, all the core library stacks. And I would argue that yes, this
*includes* libGL. So llvmpipe needs fixed, outside of any desktops.  Should
we define the core functionality better? Probably.

- The defaults should be the same.

SELinux on. Filesystem of ext4 (currently), and so forth.

And also therefore, if you're intending to ship/support a desktop use case
(which, from the F19 ARM deliverables seems to be the case), then the same
one that's the default on other primary arches needs to be available, work,
and should be the default on the new primary arch as well.
