So, the good news on this point is that we're doing a relatively good
job of keeping people current -- the work we're doing on making
upgrades smooth seems to be paying off. A little shy of 47% of mirror
checkins come from F25 (with F26 beta and Rawhide contributing another
1.5%). F24 is 15%, and F23 is 12%.
F22 drops down to 6.2%, F21 is 4.3%, and F20 is 5.9%. (F20 looks like
it's going to linger for a good long time.)
Everthing below F20 is basically peanuts in comparison (although
shout-out to F8, still holding on at around 1.6%, which puts it higher
than every pre-F20 release).
I'm not sure exactly where the cutoff should be, but I guess I'd be a
bit hesitant to move F23 away just yet. But, maybe we should make it
easier for mirrors to have only-current and current-1? (F24 is only
15%, but of course that was much higher six months at F25 launch.)

In the past we had a '1 TB limit' to what we said we offered on the
mirrors. We are currently at 2-3 times that depending on whether a
mirror can hardlink. I am very worried about how much this will grow
under the new modularity and other images we are planning to present.
