Comment 5 for bug 436981

Based on the GNOME HIG[1], it is not good to have Yes/No choices in the buttons, the button texts should be written as imperative verbs. I have been thinking on how we could rephrase the question to be more accurate, but I could not come up with a better wording.
The current primary text is "Replace your changes in '%s' with a later version of the configuration file?"
The current secondary text is "If you don't know why the file is there already, it is usually safe to replace it."
Could anyone suggest a better wording, knowing that the best would be to have the button actions as imperative verbs (like Keep and Replace, maybe Replace could be changed to Overwrite)?
