I understand that when you upload a file the correct way, it'll create a symlink for 1 directory and is actually stored in another.

My modified version is more-focused on the captive portal. I'd like to give users an easy way to change, say, a css file (captiveportal-style.css) and use SSH to swap the file manually.

Surely it's ill-advised, but since I'm going to do it anyway, what would be the best way to accomplish this? If I don't care about space, I suppose I can just copy it to both folders (forgot the folder locations off the top of my head)?

Thanks
