Re: HEADS UP: FreeBSD git mirrors demoted to beta status, need your help
This has been completed, your next pull will result in a non-fastforwardable change and I'd advise you to re-branch from origin/master instead. If you run into any trouble, don't hesitate to contact me directly.

Re: HEADS UP: FreeBSD git mirrors demoted to beta status, need your help
Just a reminder that this re-roll will happen in almost two weeks. Thanks to a couple of volunteers, I now have independent confirmation that the process is deterministic and repeatable and the switch can progress as planned.

Hey, http://www.bayofrum.net/~crees/scratch/git-show-ref.txt I hope it's what you were hoping for :) My local svn mirror is synchronised at midnight GMT (UTC). Need anything else?
