Fuel@OPNFV submodule fetching and patching
==========================================
@@ -10,98 +11,135 @@ working with upstream Fuel/MCP components (e.g.: reclass-system-salt-model) in
developing/applying OPNFV patches (backports, custom fixes etc.).
The scripts should be friendly to the following 2 use-cases:
+
- development work: easily cloning, binding repos to specific commits,
remote tracking, patch development etc.;
- to provide parent build scripts an easy method of tracking upstream
references and applying OPNFV patches on top;
Also, we need to support at least the following modes of operations:
+
- submodule bind - each submodule patches will be based on the commit ID
saved in the .gitmodules config file;
- remote tracking - each submodule will sync with the upstream remote
and patches will be applied on top of <sub_remote>/<sub_branch>/HEAD;
Workflow (development)
-----------------------
+======================
+
The standard development workflow should look as follows:
-1. Decide whether remote tracking should be active or not:
- NOTE: Setting the following var to any non-empty str enables remote track.
- NOTE: Leaving unset will enable remote track for anything but stable branch.

+If remote tracking is active, upstream remote is queried and latest remote
+branch HEAD is fetched. Otherwise, checkout commit IDs from .gitmodules.
