Rather than add a special case for boots, I'd prefer moving to a mechanism more like git or Bazaar has for specifying revision ranges. There would be various specification approaches, all of which translate into (if they aren't intrinsically) a cursor position. Then, it's modular for specifying the range by date, boot number, or any other monotonic property of the journal entries. --since=boot:-1 --until=date:2012-09-29 --since=date:2012-09-29 --until=<some-entry-id> I'll look into how hard this would be to add. Any other monotonic features we could use as a range for journal entries? The monotonic feature is important so it's possible to discover the first or last qualifying item in an efficient way like a binary search. -- David Strauss | [email protected] _______________________________________________ systemd-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/systemd-devel
