    (description "@dfn{NSD}, short for Name Server Daemon, is an authoritative
name server for the Domain Name System (@dfn{DNS}).  It aims to be a fast and
RFC-compliant nameserver.

NSD uses zone information compiled via @command{zonec} into a binary database
file (@file{nsd.db}).  This allows fast startup of the name service daemon and
allows syntax-structural errors in zone files to be flagged at compile time,
before being made available to NSD service itself.  However, most traditional
BIND-style zone files can be directly imported into NSD without modification.

The collection of programs and processes that make up NSD are designed so that
the daemon itself runs as a non-privileged user and can be easily configured to
run in a @code{chroot} jail, thus making any security flaws in NSD less likely
to result in system-wide compromise.")
