The whitespace changes are due to the trim_trailing_whitespace = true in .editorconfig

The whitespace changes are due to the trim_trailing_whitespace = true in .editorconfig

what does that mean? the files should be generated from simply running terraform apply in the user data example. I just want to minimize the amount of white space changes

Interesting 🤔

I ran tofu apply in the examples/user_data directory to revert the whitespace changes.
Doing a git diff shows this:

Maybe the Terraform is generating Windows/DOS line ends (\r\n) instead of *nix (\n).

My Github Codespace automatically stripped these on save due to the end_of_line = lf config in the .editorconfig

I can't find whats causing the line ending issues but it seems to be upstream "somewhere".

we've had this raised recently as well #2974

so based on the upstream issue linked and one solution, hopefully that will resolve it. I also updated the file extension for the purely MIME multi-part user data to .txt since having those as .sh doesn't make sense
