I'm guessing we could easily flick a switch in gerrit to cause it to
rebase instead of merge.

I don't remember any debate about it, but I'm also guessing there aren't
any hugely strong opinions in OpenStack about which is better.

The thing we'd lose is the context of which parent commit a patch was
written against. If I was to go by some of Linus's rants I'd think this
was a cardinal sin ("NEVER destroy other people's history") yet kernel
folks do this all the time by emailing around patches.

On balance, I think I'd prefer if we did switch over to rebasing.

Cheers,
Mark.
