+# Dpkg Autostart
+
+`dpkg` likes to start services after installation as the Debian convention
+dictates. This can be annoying and problematic, especially when you don't
+want services to be immediately started before custom configuration can
+be applied. Instead of disabling all services from auto starting on installation
+as the `dpkg_deb_unautostart` cookbook does, lets allow specifc services
+to be targeted.
+
+## Usage
+
+### LWRP
+
+Include the cookbook as a dependency in your metadata:
+
+```ruby
+depends 'dpkg_autostart'
+```
+
+Then, within your recipe, disable the service with the LWRP:
+
+```ruby
+dpkg_autostart 'mysql-server' do
+  allow false
+end
+```
+
+That's it. When `dpkg` attempts to start the service after install (generally
+via `apt`) it will be instructed not to. This allows the proper configuration
+files to be generated, and the service to be started after everything is
+ready.
+
+### Attribute
+
+You can also provide a list of services to disable via node attribute. Add
+the default recipe to the run list:
+
+```ruby
+run_list 'recipe[dpkg_autostart]'
+```
+
+and set the services you want to restrict from auto starting:
+
+```ruby
+node[:dpkg_autostart][:disabled_services] = ['mysql-server', 'apache2']
+```
