What’s your new distro of choice?
Seems that installer is like 90% on the way to be useful as a general installer. At a glance, seems to missing things like networking setup (as most people use WiFi these days, it seems), but at least it takes care of most things you need for a install.
Then, put dwm/[your fav. wm] on top of it, with some autoservices for bluetooth, mtp and stuff.
If AlmaLinux (or any other clone) dies for some reason, you can always move to another clone without re-installation (using their tool `elevate`).
