https://github.com/basho/riak_test/blob/master/src/rtdev.erl#L76 is the main function that does the resetting of the git repository (and stops nodes, etc).
https://github.com/basho/riak_test/blob/master/bin/rtdev-setup-releases.shcreates the necessary directory structure and git repo for rtdev.erl from a bunch of prebuilt Riak devrels. https://github.com/basho/riak_test/blob/master/bin/rtdev-current.sh adds the "current" release to the existing directory structure/repo. It also bears mentioning that the tests in the official Python client create random bucket and key names, which seems to work pretty well, but it can become troublesome when you have too many buckets and you go to list them or change their properties.
