Hmm. Since my original patch was to compile pstore support out completely, I interpreted Peter's suggestion to be allowing the user override the default even if the default is disabled. That's the assumption my implementation was based off of, but maybe I misunderstood. But if Peter agrees with your changes then I'm fine with them too.
