This makes the state.json file 1303 bytes or almost 25% smaller (when using the default spec, YMMV) by omitting default values. Before: 5496 bytes After: 4193 bytes (With cgroups#9 applied, the new size is 3424, which is almost 40% savings, compared to the original). Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
