Pi hole

Installation

https://wiki.archlinux.org/index.php/Pi-hole#Set-up_PHP

Involved services:

systemctl disable systemd-resolved.service
systemctl start nginx.service php-fpm.service
systemctl start pihole-FTL.service

Edit /usr/lib/systemd/system/pihole-FTL.service to cut out capabilities, else you will get an error:

pihole-FTL.service: Failed to apply ambient capabilities (before UID change): Invalid argument
pihole-FTL.service: Failed at step CAPABILITIES spawning /usr/bin/pihole-FTL: Invalid argument

So comment out this line:

#AmbientCapabilities=CAP_NET_BIND_SERVICE CAP_NET_RAW CAP_NET_ADMIN

and instead set them manually:

# setcap cap_net_bind_service=+ep /usr/bin/pihole-FTL
