From what I remember from years ago, If you've been using CVS, then all the files in /etc will have different version headings than SVN (e.g. something like $CVS Id ... blah blah$). The first time you use SVN, mergemaster will inquire for every single file in /etc since the version headings for SVN are different. You'll only have to tolerate this once though.
