From 5ed25ba951c5ad414f6dbe7ab18dab317a740f58 Mon Sep 17 00:00:00 2001 From: Alban Crequy Date: Wed, 14 May 2014 15:35:55 +0100 Subject: [PATCH] [PATCH v3] Implement systemd socket activation Use libsystemd-daemon and two unit files to provide socket activation for the default native unix socket ($XDG_RUNTIME_DIR/pulse/native) from the user manager. In the future this would allow to drop all the complex server location and autospawn code, and just rely on the user manager to do the right thing.
