+
+Usually autospawning for root is a bad idea, since it can easily
+interfere with other users' PulseAudio instances, but in embedded
+environments where only root exists, autospawning is fine.

+Subject: [PATCH] conf-parser: add support for .d directories
+
+This allows a configuration scheme where prior to loading
+configuration from "somefile", the parser first loads configuration
+from files in directory "somefile.d". This feature is currently
+enabled only for client.conf and daemon.conf.
+
+This makes it easier to create configuration packages in distributions
+when there's need to have different configuration in different setups.
+For example, the graphical Sato environment in OpenEmbedded-core needs
+to set allow-autospawn-for-root=true in client.conf, but the default
+configuration in OpenEmbedded-core should not set that option. With
+this patch, I can create a Sato-specific package that simply installs
+50-sato.conf in /etc/pulse/client.conf.d without conflicting with the
+main client.conf file coming from a different package.
