and when updating to nftables-1:0.9.3-7.fc33.x86_64 i get this warning: Warning: The unit file, source configuration file or drop-ins of nftables.service changed on disk. Run 'systemctl daemon-reload' to reload units.
No. This means that this update changed some systemd unit files (in this case /usr/lib/systemd/system/nftables.service) and you should notify systemd daemon to read this new unit file. nftables service is disabled by default and if you didn’t enable it yourself, you can safely ignore this warning.
