I recently updated this page:
which documents progress toward supporting Sage in Fedora.
Unsurprisingly for Fedora, that table shows that we are sticking
pretty close to upstream in most cases, although there are a handful
where we are lagging behind. We're really not that far away from
being able to support all of the standard packages. I'm currently
working on getting us a polymake that we can redistribute, and
preparing GAP packages. After that, it'll be on to Singular. If
anybody wants to help out, give me a shout.
