Minor correction: Ganeti originally used back-porting, then switched to forward-porting during the 2.1 release or so. It is not technically relevant, but since we're discussing history anyway… Yes, back-porting was very painful during the 1.2/2.0 era. Forward-porting was not chosen arbitrarily, but rather to solve a real problem (that resulted in many production bugs).

I think back-porting is more practical, but if we do it, we should ensure that the original commit ID is recorded (`git cherry-pick -x`), so that at least we have a weak trail of record. regards, iustin -- You received this message because you are subscribed to the Google Groups "ganeti-devel" group.
