Good to know, thanks.
> I have no idea where that /dev/sda in the wiki came from. It is never right for an EFI install, hopefully grub-install will ignore it, because if it doesn't, well, the result won't be pretty.
What would it do? Treat the GPT partition table as MBR and corrupt it? While definitely not pretty, that should be recoverable as GPT has a backup table hopefully not located in the first few sectors.

That's definitely a useful clarification. While it's probably obvious to the average LWN reader that a bootloader needs to be installed on whatever drive the system wants to boot from, people blindly following instructions might run into trouble here.
