From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You need to make them system users without the ability to login. Any service on your machine with a dedicated user should be a system only user with no login shell defined.

Can I use usermod to apply the -r after the fact, or do I need to remove the user and redo it correctly?
It's covered in that link, but yes.
Sorry. I made myself "instructional" videos installing things and whatnot on the live USB before installing and BOY!, watching myself go so slowly through everything and still miss obvious stuff is EXCRUCIATING.
But I know who I'm dealing with. I'm solidly average or below.
