I'm not sure if you already had plans for creating the history, but
I've generally been able to turn them around in 12 hours without
really trying too hard. I have it all running in a container/chroot
where I mount the cvsroot so I could probably get it running on EC2 or
elsewhere easily enough if we're in a real hurry. If I had a ton of
RAM and store everything in tmpfs then I suspect that it could be done
faster - ferringb's design does each package category in a thread so
the largest categories become the limiter if you have enough cores (it
does them in reverse order by size so the longest ones do start
first). At some point the fetching of cvsroots and pushing of git
repos becomes limiting - for github the push takes tens of minutes,
and the repository takes much longer to show up, though I'm sure that
could all be done faster on our infra, either via git push or letting
infra clone from a bundle.
With git replace we don't need the history to go live, and this also
means that if we find a mistake in the history we can fix it and issue
a new history. So, there isn't really a rush. But, if you don't
already have the history conversion taken care of or need it faster, I
can take care of it.
