• Subversion: How to make local changes to a file *never* check in, but have it sync with remote anyway?

  - by Niels Heidenreich

  I have a file with local changes that should never sync back to the repository because it's for my local installation only. But if that same file is changed in the repo, I want those changes to update my local copy, anyway. At the moment, the file in question always shows up in the list of changes when I want to check-in my changes, and I have to manually exclude it from the check-in. How do I make it so that I can just update, with the above restriction in place? Thanks :)
