From 263aca37ecf5f977f68d87b54f2fb30584725781 Mon Sep 17 00:00:00 2001 From: Simon McVittie Date: Mon, 9 Feb 2015 19:02:43 +0000 Subject: Optionally install systemd user units for a per-user bus The socket path used here, $XDG_RUNTIME_DIR/bus, does not match what was used in user-session-units, but is what Lennart recommended on fd.o #61303, and is also what kdbus will use for its bus proxy. Installation of these units switches D-Bus to a different model of the system: instead of considering each login session (approximately, each password typed in) to be its own session, the user-session model is that all concurrent logins by the same user form one large session. This allows the same bus to be shared by a graphical session, cron jobs, tty/ssh sessions, screen/tmux sessions and so on. Because this is a different world-view, it is compile-time optional: OS builders can choose which world their OS will live in. The default is still the login-session model used in earlier D-Bus releases, but might change to the user-session model in future. Explicit configuration is recommended. In OSs that support both models (either for sysadmin flexibility or as a transitional measure), the OS builder should enable the user bus units, but split them off into a dpkg binary package, RPM subpackage etc.; the sysadmin can choose whether to enable the user-session model by choosing whether to install that package.
