Also endeavour is not really arch with a graphical installer, or that is what I’ve seen at least.
I tried to help someone once that installed endevouros and for some reason their kernel parameters were being overwritten every time they updated, turns out that was an issue because endeavour installed dracut instead of mkinitcpio by default? I don’t know wtf was that. They ended up switching to arch after that lol.
Also their /efi directory was set as read-only to the root user, meaning that to even see if their kernel parameters were there they needed sudo lol
