I'm not seeing a BCD on the ESP, that's usually on NTFS historically
anyway. I see bootmgfw.efi, and bootmgr.efi.

Right, with a grub.cfg using configfile on the ESP to point to a
"real" grub.cfg, or BLS snippets, on /boot. Or even better would be
dynamic discovery similar to gummiboot, rEFInd, and the built-in boot
manager in Apple's firmware (talk about something that's very rarely

Yes I'd like to see GRUB on the ESP be totally generic, except for an
installer created grub.cfg that merely forwards to the real one on
/boot. Then it's on a more reliable fs, it can be mirrored, and that
one is always updated when there are kernel upgrades, rather than the
one on the ESP. openSUSE does this already, maybe also Ubuntu. Fedora
doesn't, it's main grub.cfg is on the ESP and that's the one always
modified whenever kernels are installed, and since Fedora gets lots of
kernel updates, this file is always being modified. I've tried to
encourage a different strategy!
