- use tA=...s instead of `A...` or `AttrValid=...` for time(Attr valid);
- use tE=...s instead of `EntryValid` for time(Entry valid);
- use iX instead of `NodeId: X` for inode X;
- use gX instead of `Generation=X` for generation X;
- use `[<off> +<size>)` instead of `off <off> sz <sz>`;

- use

        rx uniq: Op iX opargs
        tx uniq: status reply...

  instead of

        Dispatch uniq: Op NodeId: X opargs
        Serialize uniq: Op code: status reply...

  for received/replied messages;

- use `["file1", "file2"]` instead of `names: [file1, file2]` for filenames.

- use `xb` instead of `x bytes`

- for replied data, also log data content, but only up to first 8 bytes.
  This does not flood the log, but at the same time makes filesystem
  diagnostics easier.
