after the plain installation of nftables (ubuntu server 22.04) the permissions of the /etc/nftables.conf file are set to 755 (-rwxr-xr-x). i cannot believe that it's necessary that anyone has read and execute rights. so:
what are the correct minimum rights for nftables?
chmod 644 /etc/nftables.conf [?]
i looked through the web and man pages, but couldn't find a trusted answer.
