Re: HEADS UP: FreeBSD git mirrors demoted to beta status, need your help

Ulrich,

Are you still hoping for feedback on this?

If so I am currently setting up to run your scripts from:
http://wiki.freebsd.org/GitWorkflow#History

Let me know if that is not needed though because if I don't need to then 
I can save myself a bunch of work.

I'll report back to you on my success or not.
