Set up logrotate on Pi-hole
The pi-hole-serverAUR package comes with a "prebuilt" logrotate script here :
But the Pi-hole's logrotate will not be "enabled" until you copy this file in the "/etc/logrotate.d/" directory, causing the Pi-hole's log files to grow up infinitely.
Unless you want to do your own logrotate script, you should copy the default one into the logrotate directory in order to activate it (use "sudo" if needed) :
cp -p /etc/pihole/logrotate /etc/logrotate.d/pihole
