wow! finally something neat from journald

  Finally? The thing has an amazing amount of useful features. Let's see: * Automatic log cleanup to a desired storage size. * Automatic compression, transparent decompression. * Filtering by date, or boot number. * Log shipping, ability to see interleaved logs from multiple machines. * Microsecond precision for timestamps, multiple timestamp types and output formats. * Output in JSON or multiple other formats, for trivial parsing. * Cursors, for easily continuing parsing where you left off. * Applications can log custom fields. No need to extract data from strings then. * Captures logs that happen inside initramfs before / is mounted. * Docker containers can log to the host's journald It's pretty darn nice, really.
