So if I understand correctly:  The system I am typing on is still 
running karmic.  There is no reference in my sources.list to lucid, so 
running # apt-get dist-upgrade would NOT update my system to lucid.  
Right? 

Thanks for explaining this so well.  Thanks in advance if I am still not 
understanding.

This raises the question, I think, of when I would use dist-upgrade 
instead of upgrade.  Perhaps if something was not working or I was 
experiencing conflicts?
