Hmm, this would move the atomicity problem from one place (wifi net) to another one (SD card). Granted, there's a big difference in reliability, but it's still not fail-safe. Thinking about it a little more, do we *really* need all-or-nothing semantics on this? A user who is doing a restore obviously doesn't care much about the *current* contents of their journal. If the restore fails in the middle due to network problems, the procedure can simply be retried as many times as needed, until it's complete. rsync is smart! -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
