a) It took me a while to find out that the shutdown sometimes happens a long time (like 1 minute) after pushing the UI button. Noobs like me run into that without any warning.
b) I had some issues with my installation and as a result those shutdown/reboot buttons from the NCP UI sometimes totally did not work. That is why I asked. Think if it like asking for another way.
c) I have no idea what exaclty happens when I push that UI button. I do wonder if it’s really safe. I also do wonder if the command line “shutdown” is safe? Isnt that a pure OS command and runs the risk of hard interrupting some database or file write processes in NC?
