We certainly agree on the idea that multiple distributions, and all the
major upstreams, would benefit from a coordinated freeze. If we sit down
and agree to use the same version of the kernel, for example, that helps
the kernel community plan their merge windows and merge criteria in a
way that they have never been able to do before.
It would be substantially easier to collaborate on RC (and non-RC) bug
fixes where the base versions of major components were the same.
That said, I don't believe that any distribution should feel compelled
to go with a particular version. If Mandriva really wants to go with a
different version of X, say, then all power to them. There will be
benefits to being on a common base with others, and there will sometimes
be benefits or constraints which mandate a delta for any particular
So, coordinated *freezes* make a lot of sense for distributions *and*
However, when it comes to the release, there are equally good reasons
for different distributions to take different approaches. We each have
different policies and focuses. We treat different issues as release
blockers. We are focused on different use cases. All of those will drive
differences in release dates.
So, I strongly support your Option 2 as the model, but I don't think it
leads to exactly the same freeze-and-release dates. It leads to a shared
freeze date where we establish how much common signalling we can send to
upstreams, followed by improved collaboration both with other
distributions and with upstreams, and varying release dates.
Is that a bad thing? Well, I think some people will say a distro is
*better* if it releases later. Others will say a distro is better if it
releases on a schedule. There have been so many distributions around for
so long and yet each of the majors, including both Debian and Ubuntu,
have loyal and passionate users. I don't think this is about trying to
convince users to switch - they believe in the brands they believe in,
to the credit of both groups, not to either detriment.
