Sorry about before. Thunderbird & Office365 are fun...
 
We're mostly running RHEL6 with the Red Hat 2.6.32 kernel, a shrinking handful 
of RHEL5 boxes with
the 2.6.18 kernel, and an even smaller number of RHEL7 machines running 3.10.0. 
We're also planning
on replacing our Solaris 10 OpenAFS database servers with RHEL6 machines within 
the year.

Since support for RHEL6 doesn't end until 2020, we'll still like to see Linux 
2.6 support continue in
OpenAFS 1.6 at least until then.
