I'd go further than this: it was originally designed as a stopgap to have FreeBSD work in an EFI world when we didn't support the standard UEFI interfaces and did not have a straightforward way for loader.efi to find its script/configuration files in a different partition or filesystem. As far as I recall it was never intended to be a permanent part of the UEFI boot process. We'll probably reacquire a small first-stage UEFI boot component: the UEFI Secure Boot shim loader. But it can load loader.efi from the ESP and won't be used outside of Secure Boot configurations. > Moving to a > 'standard' setup for EFI would be a good first step, as well as having a > script to do this both for when the ESP is mounted in a non-standard place, > as well as for when it's not mounted. I'm not sure how far we have to go in catering to non-standard configurations. I completely agree we should have a standard EFI configuration and should support seamless upgrades in that configuration. For other cases I'd personally just ensure we've fully documented the components and processes.home | help
