This means +that checking out code, then running `verify-commits.sh` against `HEAD` is +_not_ safe, because the version of `verify-commits.sh` that you just ran could +be backdoored. Instead, you need to use a trusted version of verify-commits +prior to checkout to make sure you're checking out only code signed by trusted +keys: + + git fetch origin && \ + ./contrib/verify-commits/verify-commits.sh origin/master && \ + git checkout origin/master + +Note that the above isn't a good UI/UX yet, and needs significant improvements +to make it more convenient and reduce the chance of errors; pull-reqs +improving this process would be much appreciated.
