We need to add Dan Berrange's size reporting patch to the mkfs.jffs2 that's in rawhide, or something like it. We need to be able to measure filesystem size usage after an image is generated so we can measure regressions and figure out what kinds of compression we're getting in flash.
David, did this get added to your mtd tree yet? I seem to remember you saying that you were doing it, just wanted to follow up to make sure it was.
David told me that this patch is in extras now.
