Does your approach include a blessing tool?
Not that I know of. The grub image (a copy of GRUB's `core.elf`) in the root of the OF bootstrap partition is configured in the OF environment var `boot-device`. OF therefore knows what file to boot and from where.
I want to avoid messing around with the NVRAM as this approach is very fragile.
Why is that?
A blessed bootloader, on the other hand, is automatically displayed in the boot menu and booted unless any alternatives are present. It's therefore much more robust.
I don't know if the described approach is more robust, but I believe you can't have both FAT as OF bootstrap partition **and** blessing. Reading through [4]: ``` [...] Furthermore, the CoreServices folder is "blessed", which means that it's directory ID (analogous to an inum in FFS terminology) is recorded, in the HFS+ volume header. [...] ``` ...makes it look like it is specific to HFS(+). I am hence not even sure if the graphical boot menu will work with FAT as OF bootstrap partition. I never used it because I booted the machines from OF. Cheers, Frank
