How to prevent blogdown from rerendering all posts?

Question

Background:

I am featuring a blog built on @YihuiXie\'s R package blogdown.

Problem:

When I render_site()

Answer 1

blogdown::serve_site() tries to rerender some of my old blog posts after I reset my computer and re-downloaded the code from github.

By using blogdown:::build_rmds("content/post/{file_name}.Rmd") I was able to render single Rmd files to html. To check the results I run hugo server in the terminal window.
