What issues were you worried about?
The part that I left out, to keep things simple, is that our actual repository structure is the following: - developers work in their local clones and push to Gerrit (for code review) - commits which pass code review get merged by Gerrit, and auto-replicated to a couple of places (specifically, an upstream repo in our colo for deployment purposes, and a private GitHub repo, for redundancy) Gerrit has its own embedded Java-powered Git daemon, but it doesn't support post-receive hooks like the native Git daemon does, so in order to run arbitrary code like we'd need to, we have to tell Gerrit to replicate into some other (non-Gerrit) repo which is capable of running the hook. This was the "scratch" repo that I described above, and I was thinking of putting it on the same machine as Gerrit with a "file" URL and an appropriately configured receivepack property as suggested here by Shawn Pearce. (Gerrit _does_ have its own hook system, but I'd feel more comfortable writing this using a standard hook, as I think the code will be more straightforward, and it won't couple us any more tightly to Gerrit than we already are.)
