Red Hat continues to provide patches for RHEL within the "Extended Life
Cycle" (years 8, 9 and 10), but it's an optional add-on.

So another interpretation of the above with Nick's proposal could be 10
years on RHEL.  (though obviously I'm biased in favor of RHEL)

Approaching this from another angle: please do add me to the "nosy" on
any compatibility bugs with running latest python code on RHEL.  I'm
also looking into getting RHEL buildbot machines, FWIW.

The other compat issues are in the toolchain: e.g. very recent versions
of gcc .  In downstream Fedora, we tend to be amongst the first to run
into new compilation warnings (and, occasionally, "exciting"
code-generation bugs...)

But this tends to be the opposite kind of problem: beginning of life,
rather than end-of-life, and these sorts of things will need fixing for
every Linux build eventually.

FWIW, I'm trying to keep Fedora's "system" python 2 and python 3 builds
as up-to-date as reasonable, so Fedora users will (I hope) be running
fairly recent code python as is.  We have 2.7 as /usr/bin/python as of
F14, for instance.

Hope this is helpful
