Hi, For the entire time I've been maintaining projects on Github I have had this deeply rooted unhappy feeling every time I clicked the merge button, because I just really hate what the merge commits do to `git log`. IMO, merge commits make sense if you're the Linux kernel, but for smaller projects are just ugly noise.
Github actually recently improved this: https://github.com/blog/2141-squash-your-commits However, over the last few weeks (before the Github change) I've been switching more of the projects for which I am a primary maintainer over to my personal instance of Homu: https://github.com/servo/homu known as @cgwalters-bot. Even after the Github change to support squashing, it has the nice advantage of implementing a "merge queue" and testing each merge before commit. Another benefit of this that I like is being able to just drop an "r+ $sha" in a comment and forget about the PR (assuming the tests pass). Anyways, the plan is to move this functionality for Project Atomic into atomic-bot at some point (hopefully soon). In the meantime though, rpm-ostree is one example user of this: https://github.com/projectatomic/rpm-ostree/pull/256 So if you see some repos using this, that's the background.
