This is what dispatch-conf will do if you give it time to work. For 
dispatch-conf to work you need to initialise it first. It works with 
three-way diffs, so without a reference (which gets created the first time a 
config file is updated with dispatch-conf) it doesn't work. For the rest, I 
suggest you write up a patch to dispatch-conf to allow it to ignore certain 
files. However it normally works quite well with fstab as the default one 
hardly changes, and you'd want to know about those changes anyway.

Well, go ahead
