dbus failure to start after crash

[ld-temp-q6x8@…]

There is already a ticket (14163) related to this issue, but it hasn't been updated in 2 months and I can't figure out how to annotate it. After a forced reboot, dbus doesn't automatically restart because the PID file, /opt/local/var/run/dbus/pid, doesn't get deleted. Since dbus is running as a launchd job, this file isn't needed and shouldn't exist. The launchd item itself and the system.conf files also need to be changed. There's no need for the dbus.wrapper script, which seems to be a relic of pre-launchd times. dbus-daemon should be called directly from org.macports.dbus.plist, and the lines in system.conf that cause it to drop privileges, fork into the background, and write a PID file should be removed. If there was any useful documentation of Trac and I knew how to attach files to this ticket, I'd submit proposed replacements for org.macports.dbus.plist and system.conf, but I think it's fairly clear what needs to be changed. Thanks.
