Sorry to be late in replying to this thread but it's been a week of travel.
So I've had a number of people ping me about bringing support for the
XO-* devices into Fedora as a supported platform. I think it's
reasonably achievable but will likely need some assistance. I think
it's probably worth starting a separate thread but I'll put some quick
points here, if people generally think it's worthwhile I'll kick off a
more detailed thread.
The new Fedora structure for F-21 and moving forward is likely a
better candidate for longer term support for things like a XO-*
distro. There is planned a number of improvements from both a
technical and procedural PoV but it's still a little in flux.
>From a tech PoV specifically discussing the various XO-* as a HW
platform here's some bullet points:
- Need to rebase to a newer kernel from a supportability PoV (wifi
- ARM wise there's people working to upstream the MMP2/3 platforms the
ARM XOs are based on.
- The etna_viv is likely the best driver for the ARM devices and in
the F-21 timeframe should support even gnome3/mesa
Not sure of the x86 kernel staus, I seem to remember dsd had kernel
status documented on the wiki.
OOB should be relatively easy to support moving forward, not sure
about olpc-update but I suspect that with decent OOB support most
deployments actually spin their own custom releases so I'm unconvinced
of it's importance.

Well F-20 will be supported for quite some time due to the extended
release cycle of F-21 so I suspect it'll be supported until the end of
2015 given that F-21 isn't due until October and most of the work will
translate directly into F-21 with little effort.
The thing to remember is that Sugar and the userspace in Fedora is in
good shape for Sugar which means that it's really only HW support and
specific use cases that needs to be dealt with. I'm not sure what the
state of Sugar is in other distros.
