How are ~5 minute ZFS snapshots significantly better than git log --patch to look at your history, combined with git checkout $COMMIT to get the code to perform any tests required? (Or, if you have a reliable automated test, git bisect start HEAD $KNOWN_GOOD_COMMIT -- && git bisect run $TEST will automatically find the error for you.) [0][1] And remember that the git checkpoint creation process is -at its most verbose- running git commit -m "C" [0] You can use points-in-time as commit references, like 'master@{30 minutes ago}' or 'HEAD@{2016-01-01}' [1] And even if you don't have a test, you can easily manually run the bisect machinery.
