Hey Steve,

source-repositories is your friend here :) (check out
dib/elements/source-repositires/README). One potential gotcha is that
because source-repositires is an element it really only applies to tools
used within images (and os-apply-config is used outside the image). To
fix this we have a shim in tripleo-incubator/scripts/pull-tools which
emulates the functionality of source-repositories.

Example usage:

* checkout os-apply-config to the ref you wish to use
* export DIB_REPOLOCATION_os_apply_config="/path/to/oac"
* export DIB_REPOREF_os_refresh_config="refs/changes/64/145764/1"
* start your devtesting

HTH,
Greg
