DESCRIPTION

+Installs and configures Dan Bernstein's DNS tinydns, aka djbdns. Services are configured to start up under runit, daemontools or bluepill.
+
+CHANGES
+=======
+
+The various recipes now support multiple service types. This is controlled with the `node[:djbdns][:service_type]` attribute, which is set by platform in the default recipe.
+
+ArchLinux support has been added, as well as naively attempting other platforms by source-compiled installation with bluepill for service management.
REQUIREMENTS
============
Platform
--------
-Known to work on Debian, Ubuntu, Red Hat and CentOS.
+Known to work on Debian, Ubuntu, Red Hat, CentOS and ArchLinux.
Cookbooks
---------
* build-essential - for compiling the source.
+* ucspi-tcp - installation of ucspi-tcp now separate cookbook.
* runit - for setting up the services.
+* daemontools - alternative service configuration.
+* bluepill - alternative service configuration.

+RESOURCES AND PROVIDERS
+=======================
+
+`djbdns_rr`
+-----------
+
+Adds a resource record for the specified FQDN.
+
+# Actions
+
+- :add: Creates a new entry in the tinydns data file with the `add-X` scripts in the tinydns root directory.
+
+# Attribute Parameters
+
+- fqdn: name attribute. specifies the fully qualified domain name of the record.
+- ip: ip address for the record.
+- type: specifies the type of entry. valid types are: alias, alias6, childns, host, host6, mx, and ns. default is `host`.
+- cwd: current working directory where the add scripts and data files must be located. default is the node attribute `djbdns[:tinydns_internal_dir]`, usually `/etc/djbdns/tinydns-internal`.
+
+# Example
+
+ djbdns_rr "www.example.com" do
+ ip "192.168.0.100"
+ type "host"
+ action :add
+ notifies :run, "execute[build-tinydns-internal-data]"
+ end
+
+(The resource `execute[build-tinydns-internal-data]` should run a `make` in the tinydns root directory (aka cwd).
+

+The default recipe attempts to install djbdns on as many platforms as possible. It tries to detrmine the platform's installation method:
+
+* Older versions of Debian and Ubuntu attempt installation from source. Ubuntu 8.10+ will use packages, as will Debian 5.0 (lenny) +.
+* ArchLinux will install from AUR.
+* All other distributions will install from source.
+
+The service type is selected by platform as well:
+
+* Debian and Ubuntu will use runit.
+* ArchLinux will use daemontools.
+* All other platforms will use bluepill.
+
+Service specific users will be created as system users:
