the ibt is needed if you are using nvidia+intel and kernels newer than 5.18… (but only some generetion of intel cpus is affected, se we added it, just in case);
the early loading just enables early loading of the specific modules that we added into mkinitcpio… more info here;
and since this was a fresh install and i didnt know if you are up to date to the latest, we did that too… and thats it…
