Hi, Current grub-installer script will overwrite boot sector of wrong partition for Intel based Mac users. This is not so nice thing to have for release.
I now have tested and updated patch for this bug and test d-i image at: http://people.debian.org/~osamu/d-i-osamu-grub2.iso http://people.debian.org/~osamu/grub-installer_1.35.all-but-po.diff.gz It works! I also made full patch including translated text for all languages and put at: http://people.debian.org/~osamu/grub-installer_1.35.all.diff.gz (No code change but just po and comment out of set -x.) So this patch will not degrade translation status, and please consider this fr inclusion. Patch is based on unstable 1.35 package. --- Here is details. Since my bug report and my patch concept, I spend some time to recall d-i testing tricks. (I made diunpk and dipk script: http://wiki.debian.org/DebianInstaller/Modify/CD ) My initial patch had typo but my idea was confirmed right. 1) GRUB2 device name has no offset and need adjustment as proposed. 2) rescue mode now offer boot loader installation on GRUB 2 too. 3) 30_os-prober script of grub-pc is fine but it must be run after rebooting system to be more useful. (see below) 4) gptsync needs to be installed and run from shell console in chroot but this can be done by rEFIt chain bootloader side too. Thus d-i is usable on MacTel (Intel Macs). I intentionally left not-so-precise statement of "first extended partition" under GPT. This is because this will create translation headache. Osamu FYI: If os-prober package is initially installed and a post reboot hook script is made to run update-grub script, grub.cfg is generated correctly without 30_otheros from grub-installer. This will make cleaner installation code. This should be post-lenny thing.
