I tried 'damo args damon', but it doesn't save the DAMOS schemes information. 'damo report damon --json' provides more detailed information, but its output cannot be read by 'damo start --kdamonds'. I'd like to know if there is currently any way in damo to save the DAMON SYSFS configuration that can be correctly read by 'damo start --kdamonds'. If not, would it be worth adding one?
