Workaround for macOS High Sierra Root Bug

This is a short blurb intended mostly to help out friends and family. Earlier today Twitter caught fire as a massive bug was reported in the latest version of MacOS (macOS High Sierra) by Lemi Orhan Ergin (Thanks for the heads up, sir!):

An update to the OS cleared the root account password. You can do as suggested in the tweet, as well as even log into your Mac using root with no password. This is a very serious security issue, you need to address this right now. I panicked when I saw this and tweeted my panic! Typo and all.

Update: More reason to worry, check out this video and thread:

There is an easy workaround. Just set a root password! Follow this post to see how it's done.
