Yeah this is sort of funny because Linux used to let you delete EFI vars, bricking motherboards, since it mounted them to the root filesystem. It’s since been patched in every motherboard, but sometimes full control is more dangerous than “haha I can just reinstall”

    There are now. In 2016, there were motherboards that didn’t properly implement the UEFI standard, outlined in the link I provided, and those motherboards would be bricked were someone to delete the EFI vars. The motherboard would never reach POST on boot
