Moving Bugzilla to git?

Hi Mark,

I support this move, although I have some comments on making it work well.

I think we should master it (insofar as git has a master) on Mozilla's
git server (assuming it's up by now?) and mirror to github. That gives
better continuity in the face of problems on a service we don't control,
but also the exposure that github brings.

Are you planning only to move trunk to github, or also a number of branches?

What is the current status of the CVS mirror?

My point is: if some old installations are still stuck on CVS, can we
make it so they don't have to make _two_ VCS transitions to get to git?
In other words, can we make the lowest-numbered branch available via Git
be the same as the highest-numbered branch available via CVS?

I can't work out what the highest-numbered branch available via CVS is;
trunk has the version number 4.5.1+, which I assume is because there's
some sort of mirroring going on.

Yes; I am very much in favour of the "change one thing at once" style of
migration where the user moves VCS systems without making any other
change, and only then performs some sort of upgrade.
