Yeah, I have been working on the RHEL and Fedora installer since 2013 and already back then it had a long history almost lost to time - the git history goes all the way back to 1999 (the history was imported from CVS, as it predates Git) and that actually only cover the first graphical interface - it had automated installation support via kickstart and a text interface long before that, but the commit history has been apparently lost. And there seems to have been even some earlier distict installer before Anaconda, that likely also supported some sort of automated install.

BTW, we managed to get the earlies history of the project written down here by one of the earliest contributors for anyone who might be interested:

As for how the automated installation on RHEL, Fedora and related distros works - it is indeed via kickstart:

Note how some commands were introduced way back in the single digit Fedora/Fedora Core age - that was from about 2003 to 2008. Latest Fedora is Fedora 43. :)
