 openresolv is an optional runtime dependency -- you need it if you want
 to use to use wg-quick's DNS option.

+The wg-quick script needs at least nft 0.7 installed, if using nft.
+Slackware 14.2 ships with nftables 0.6.  As such the build script
+will patch wg-quick to always fall back to iptables.

+If you have nftables 0.7 or newer installed (i.e. you are running
+-current or a modified 14.2 installation), you may want to leave
