Ah! yes so it does. Was not aware of this, but I guess what Kaushal adds
below maybe valid as well. Will let you folks arrive at the right
tarball (and possibly right location to pick it up from). The tarball
mechanism as such (as discussed with Kaleb) stands I assume.

Agreed!

I would think we follow what we need to do for the gluster package (and
its sub-packages) as it stands now. If there is an important enough fix
(critical/security etc.) that requires a one-off build (ie. not a
maintenance release or a regular release) we respin the whole thing
(which is more work).

I think if it is a GD2 specific fix then just re-spinning that
sub-package makes more sense and possibly less work.

I am going to leave the decision of re-spinning the whole thing or just
the GD2 package to the packaging folks, but state that re-spin rules do
not change, IOW, if something is critical enough we re-spin as we do today.

Yes, let's not do this ATM. There seems to be very little advantage to
making this it's own package as it stands.
