git - When a commit to revision control requires a developer to change their own config

Question

What's the best method to notify other developers when a change committed into revision control requires some specific additional action by the developer getting the update e.g. modify a local config file not in version control?

I'm currently writing it in the commit message, but it seems like this could easily be missed. Do any revision control systems provide a better way of doing this?

How do other people do this, or should there never be any necessary changes that are outside of revision control?

I'm using mercurial but answers from those using other forms of revision control would be useful too.

Answer 1

There should rarely be changes necessary that are outside of revision control. For the rare cases where they are, use the regular communication channel the developers have (like mailing list or IRC channel or something similar). Every multi-developer project needs such thing anyway.
