I have just come through an epic installation disaster of Rocky 8.4, I have been running a very stable Centos 7 installation for many years on a 1TB raid1 mirror (two seagate 1TB) with other mirrors for data backup, my hardware is 2 2080Ti’s, 128GB ram, i9-10980XE CPU, ASUS SAGE mobo. So, I thought I would upgrade the O.S. to Rocky, first, I attached 2x M2 ssd’s and disconnected all the other drives, thinking that I might make a raid1 from the SSD’s, but after trying multiple times with the USB boot of Rocky and not having any luck, I decided to install to one ssd which was successful, but when it came to rebooting after the install all a got was screen lockup, I found that if I booted to a TTY, then I could start Rocky with “startx”. I finally figured that it was the video drivers which were causing the problem, so I downloaded the driver from NVIDIA, blacklisted nouveau, installed the NVIDIA driver at the TTY, finally got into Rocky, but I couldn’t change the resolution and the NVidia app wasn’t installed, Rocky then became very unstable, I tried again to install the NVIDIA driver, but then I got a lockup just before the login screen, it was as if the video drivers were not compiled for the new kernel which was not the case as I had just installed them which also compiles the modules. So, bottom line, after two days and countless hours of trying, I am back using good old Centos 7.9, Also I might add that I am not a Linux noob, I have installed the o.s. and drivers many many times before without any issues, looking back I think it had something to do with the UHD screen (4k) and the fact that the nouveau driver was having problems with it. ---

Got it all sorted, now I am on Rocky from Centos 7, the first issue was the fact that you can only boot a Raid 1 as a normal bios boot, but nvme can only be used in Uefi boot mode unless you do a hell of a lot of manual work, which I didn’t have the energy to do, thus I booted with a single nvme (1TB) M2 drive. The second problem was with the Nvidia drivers which RHEL 8 docs instructed to use, these clearly didn’t work and modified a lot of init files, even after removing these drivers the modified files weren’t restored, so after about 10 full install attempts, I followed the same manual method of installing the drivers as I had with Centos 7 and it worked the way you would have thought, so the docs from RHEL 8 are a no go for me in future. ---
