RPM heritage

One of the confusions, at least initially, was how to find the correct git repo, that was ancestral to the XS-0.7 School Server release at http://fedora.laptop.org/xs/stable/olpc/xs-0.7/source/.  The git folder at https://dev.laptop.org/git/ includes numerous packages with names similar to the released packages.

James Cameron suggested that it really was not difficult, beause the git commit id is included in the RPM name.  Following this lead I wrote a little script which downloads the most likely candidate, and searches the git log for a match.
The correct sources can be  downloaded using the script:

#!/bin/bash
#script to verify lineage of git clones pulled from OLPC Boston
#grep targets are the git tags embedded in xs-0.7 srpm names at
# http://fedora.laptop.org/xs/stable/olpc/xs-0.7/source/
