I'm not able to force anyone here to do anything. Therefore, I have to
encourage good practice entirely via "carrots". This works best
when we
align with the academic year -- a release in the spring, current
through the
following summer to allow time for upgrades. Ideally, *two* years
and a
summer, but I understand that's not practical.
As it is, what will happen is: whatever Fedora release is current
as of
June-July-August will get installed on people's systems, and, with
goading,
upgraded the next summer. If the actual Fedora release happens to
be new in
June-July, the 13-month plan will be great, but if the latest
release was
from, say, January, that leaves a big hole in which systems *will* get
broken into.
