Of course not. I haven't implemented this particular mechanism yet. That's why I need people like you to test the mechanism so I can implement it later. If it already worked, there wasn't anything to do in the first place :). > I think this is because only when yaboot is chosen as boot loader, the > `hfsutils` package is actually installed: Yes, this mechanism is part of the yaboot-installer script. > With GRUB selected (note the time stamps, this actually happened earlier > than the yaboot installation, so the `hfsutils` package wasn't already > installed at > this time but is really no dependency of Grub!): Of course, it isnt'. As I said, the mechanism isn't there yet. We have to implement it first. > I don't know, why the HFS partition is not formatted at the end of the > partitioning step, which would IMHO make more sense. Because it hasn't been implemented yet and the current mechanism is that the formatting happens in yaboot-installer. > I also saw the following message during GRUB installation: > ``` > It seems that this computer is configured to boot via EFI, but maybe that > configuration will not work for booting from the hard drive.

This error message is bogus. You don't have EFI on PowerPC Macs.

I have already successfully installed GRUB on my POWER7 machine with an 8 MiB PReP partition. PReP boot partitions also aren't focus of this discussion as I can easily test PReP myself.

Check your device.map. grub-installer doesn't have any mechanism yet to find the boot partition on NewWorld Macs. We need to implement that. On supported systems, grub-installer will prompt with a list of possible target devices. The device name "dummy" also gives it away. Just switch to a shell and try to install GRUB with grub-install providing the proper target device. Adrian -- .''`.
