The minimal installation ISO for Rocky Linux is fine…unless you’re installing to a system with only WiFi networking. The installer will let you connect to the network, but when you reboot after the installation, WiFi won’t work.
However, this is simple to fix. Once you get to the end of the installer and have a “Reboot Now” button—don’t hit it yet!—press Ctrl-Alt-F2. This will put you at a command line prompt.
Enter the command chroot /mnt/sysroot. Entering the chroot makes the next command act as though that directory were the root directory: dnf install NetworkManager-wifi. Then exit the chroot.
Now you can reboot (don't forget to remove the installation media).
