   Hmm.  I must be misunderstanding something.  I put a replacement  
adduser.conf into the right place, and can verify on the booted  
LiveCD image that the change is in place.  If I run, on the running  
LiveCD system, a command:

adduser --add_extra_groups garnob

   After asking bunches of questions, garnob is in fact put in group  
disk.  But, the user that came up in the system in the first place is  
still only a member of dialout,cdrom,floppy,audio,video,plugdev, and  
the group that was created with their UID as GID.  So, something  
about the adduser that the system is invoking at boot doesn't work  
quite the way I'm expecting it to.

   Any thoughts?  Thanks...

   BTW, the change I made to the adduser.conf was to add a line:

#EXTRA_GROUPS="dialout cdrom floppy audio src video lp src users"
EXTRA_GROUPS="dialout cdrom floppy audio src video lp src users disk"
