The /boot partition is FAT32 due to RedHat’s stupidity but that’s neither here nor there. The point is that regular users don’t know how to boot into a previous version of the OS. Yes, I know you just have to select it on GRUB but a black screen with a list of kernels qualifies as broken for regular people.
Yep. That’s what I’m saying, Linux isn’t ready.
Your installation is probably quite old. It used to be like that but now the default is mounting the ESP to /boot. The old way makes way more sense to me, btw.
