Patch migrated from Desktop, where it was listed as:
#owner:yippi date:2007-09-06 type:feature 
# System services are disabled by default in Solaris configuration since
# they are not yet supported on Solaris.

See comments embedded in patch below for more info.

Not suitable for upstream, need to determine if we should enable on Solaris
in the future.

   <!-- We use system service launching using a helper -->

+       To support this feature as it is on, it would be necessary to create a
+       messagebus user and configure the D-Bus module to specify the
+       with-dbus-user=messagebus option.  This causes the D-Bus system daemon
+       to run as this user and use dbus-daemon-launch-helper when privilege is
+       required.  Solaris does not include anything that uses system services,
+       so this would only be needed if you wish to wished to use an application
+       that required it.
