centos8 – CENTOS 8 Stream: How to get “root” user to appear on the GUI Login page?

I found this:

and I was able to get the “root” user to appear on the GUI login page.

The /var/lib/AccountsService/users/ directory had several files that were named the same as users, in addition to a file named “root”.

So I removed all the files except the one named “root”, and I edited the file named “root” to contain:

id='centos'
version-id='8'

[User]
Session=gnome
Icon=/root/.face
SystemAccount=false

(the “false” seems to be critical!)

I then bounced the machine and then the “root” user appeared on the GUI login page (along with the other users).
