We need to track down that error above and figure out what it means.  It could 
be that groupadd is attempting to run a system helper that it shouldn't be. 
(nscd should never be consulted when we are running through pseudo for 
password/group calculations...)

Ya, that is definitely broken.  W/o the files then the groupadd/useradd won't 
function properly and the install is likely a failure.

On other systems I work with, we -always- install the passwd/group files onto 
the system -first-.  Then we perform the regular installation procedure.  I 
wonder if we may have to do something like that within oe-core to force the 
proper ordering.

It would be interesting to me to see the install order that was selected in this 
case.  It could be that opkg either is missing some critical dependency 
information -- or perhaps what we need simply can't be specified.

In other systems I've worked with, the base-passwd packages has been a 
requirement of the libc package.  Since libc generally gets installed early in 
the process it usually enforces it to be first.  I'm not sure if OE-core has 
that same dep.  (Maybe we simply need any package that has files != root:root 
have a dep on the passwd files?  Just thinking outloud here.. I'm not sure thats 
really a good idea.)
