I was little sloppy in that last posting which may have lead to confusion. I
meant to say that when a parameter has a single argument, putting quotes around
it seemed to cause a problem. In my case I was using the parameters
--packages-lists "xfce-desktop" and --packages "firmware-iwlwifi" which didn't
work. I tried on 3 separate occasions and all 3 failed, producing a 127 mb
image that was apparently a base system without the xfce desktop. When I used
the parameters --packages-lists xfce-desktop and --packages firmware-iwlwifi
(without quotes) the build worked as expected and built an image >800 mb that
when booted, had the xfce desktop. From my memory there was no difference in
my attempt to build the image other than the use of quotes with parameters that
had a singular argument. Now it is possible that something else was going on
but I am not aware of what other differences there could have been between the
attempts to build.
