Hi all, I am using latest 2.x version of Bird and I have a question about graceful restart. I have `graceful restart on` for BGP protocol and I currently perform below steps when I want to utilize it: 1. birdc graceful restart 2. systemctl start bird.service According to the documentation I need `-R` command-line option, thus I have adjusted systemd unit file accordingly: ``` ExecStart=/usr/sbin/bird -R -f -u bird -g bird ``` How does the aforementioned command-line option behave when `birdc graceful restart` is not issued? I scanned the code to understand it and I think bird is smart enough to know that a graceful restarted was not requested and it doesn't do anything during the startup. While I was testing graceful restart functionality, I noticed that even without the aforementioned command-line option the upstream peer does not remove the routes until restart timeout expires. So, I was wondering if that option is real needed thus the question. Regards, Pavlos
