Maybe I'm answering my own question here. If I go to the latest factory build directory http://www.gumstix.net/factory_images/overo-201004270808/ and then look at the log on gitorious/gumstix-oe, I find that the last commit before that datestamp was http://gitorious.net/gumstix-oe/mainline/commit/56bec45084597c12dff03605049090e5375f126e. Presumably I can tag that commit and baseline from that point to anchor myself to the factory build.
I've just started a commercial project on the Overo and am wondering how others are handling version/change control on the Gumstix. After getting started, I realized that the OpenEmbedded dev repository, the www.sakoman.com kernel and other components are open branches with no labelled versions from which to baseline. I did find the stable/2009 branch of OpenEmbedded and am working on a build to see how that works, but it would be nice if gumstix-oe had its own stable branch to track OE stable/2009.Any suggestions would be appreciated.Regards,
