Well, I am trying to use etcupdate for at least 2 or 3 years and I 
regret it every time. I am taking care of about 20 machines and every 
time I need to upgrade them and use etcupdate there are some issues or 
at least unnecessary conflicts that I must fix manually. Many time in 
file that I never edited. For me personally the mergemaster worked in 
much better way.
