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.

For reference/correctness related things, I would leave it to experts on specs, and init.d scripts to respond.
