>Description:
	Searching why firefox 2 stops working after a big portupgrade
	(up from 2009017) with the message:

process 946: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/db/dbus/machine-id": No such file or directory
See the manual page for dbus-uuidgen to correct this issue.
  D-Bus not compiled with backtrace support so unable to print a backtrace

	I found that this file ist generated by dbus-uuidgen during the
	execution of pkg-install in ports/devel/dbus.
	For our diskless machines /var is set up by /etc/rc.d/var which
	results in a non existing directory /var/db/dbus. Fixed that
	there is no automatically setup for /var/db/dbus/machine-id
	as dbus-uuidgen is only executed during pkg-install.

>How-To-Repeat:
	See the code from /etc/rc.d/var, ports/devel/dbus/pkg-install and
	/usr/local/etc/rc.d/dbus. Or set up a diskless machine and look
	into /var/db.

>Fix:
	I think the easiest way should be to add code to /usr/local/etc/rc.d/dbus
	to make the directory and than call dbus-uuidgen --ensure.
	This will not fix applications using dbus methods if dbus is not running. 
	To fix that, and possible other diskless setup problems with ports, it
	may be neccessary to install a "/usr/local/etc/rc.d/diskless" which
	handles that.
