Avahi startup problems worse in the past few weeks.

[TechyTech]

Over the past few weeks of build updates I've been noticing that Avahi has been having increasing problems starting automatically after reboots (more so than the usual temperamental behavior Avahi tends to exhibit).  What was once intermittent, or just long delayed after all interface transitions complete, has now become fairly consistent.

It either takes a long time to start, with several restart attempts noted by errors in the system log, if it starts at all.  When it fails to start automatically, manual start works fine.

The only entries I see in the system log when Avahi wont' start are:

Found user 'avahi' (UID 558) and group 'avahi' (GID 558). 
Successfully dropped root privileges.
avahi-daemon 0.6.31 starting up.
WARNING: No NSS support for mDNS detected, consider installing nss-mdns!
dbus_bus_get_private(): Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory
WARNING: Failed to contact D-Bus daemon.
avahi-daemon 0.6.31 exiting.

When started manualy, there is the NSS error in the log, but otherwise starts up with no problems.

Avahi configuration is at defaults, and I've tried both re-installing the package and deleting and installing the package with no changes in behaviour of startup problems.

I'm having the same problem, same log entries, pfSense 2.4.3-RELEASE-p1 running on an SG-2440

There is a new version of the Avahi package under review that should address this.
