nftables Logs on Alpine Linux

If your nftables “log” action isn’t logging traffic on Alpine Linux, it may be because sysklogd isn’t running:

# Install the init script
root@logic-b0mb:~# apk add sysklogd-openrc
# Make it start at boot
root@logic-b0mb:~# rc-update add klogd boot
# Start it now
root@logic-b0mb:~# rc-service klogd  start

Woo!

root@logic-b0mb:~# tail -n 3 /var/log/messages
