That is a sweet thing to read as first thing the email :-)

Most probably. The dates points difference of ~18 months between them.
Surely some improvements would have gone into the code. (~1000 patches in
an year)

Trying to check git log inside glusterfs' spec file and not able to find
any thing. Looks like the diff is mostly with CentOS spec.

IMO that is a good news. I don't think it would be an issue all of a sudden
after 4-5 years.

We just need to start 'glusterd' service in later versions. So, if it is
working, it would be fine. For reference/correctness related things, I
would leave it to experts on specs, and init.d scripts to respond.

For most of the emails, we end up recommending to move to a latest,
supported version, but considering you are not facing an issue on top of
filesystem, I wouldn't recommend that yet :-)
