Ah, so that's why the kernel segment (which isn't text btw, it's rwx) is called "load" :-P (Not convinced. Some arch just got it wrong, and many others blindly copied it? That sounds a lot more likely imo.) > Regardless, it is an entirely internal-to-the-linker-script > identifier, so I am just consolidating on a common name with the least > number of collateral changes. Yes, that's what I'm complaining about. Names *matter*, internal names doubly so. So why replace a good name with a worse name? Because it is slightly less work for you? Segher p.s.
