Notes about Debian's PowerDNS package
-------------------------------------

 + Introduction

PowerDNS is a powerful DNS server, it has the ability to serve data
from different backends, including MySQL, PostgreSQL, LDAP etc.

 + Configure

The configuration for PowerDNS is separated in different files. In
/etc/powerdns/pdns.conf are the base server settings, the configuration for
specific backends could go into any other file (ending in .conf) in
/etc/powerdns/pdns.d/. launch= settings can be chained by using the launch+=
syntax.

 + Chroot

PowerDNS can run in a chrooted environment, but this has some disadvantages.
It is not easy to connect via a socket to another service like MySQL or
PostgreSQL. When using the sqlite backend, the database needs to live inside
the chroot. With systemd, the service startup notification currently does
not work for similar reasons. If you don't have these restrictions you can
enable the chroot option.
