when installing a new squeeze system i noticed that it's not possible to make grub install into multiple MBRs using the installer. since my boot partition is on a RAID1 i'd like grub to be installed with redundancy, too. IMHO ubuntu supports this. workaround: after install: for DISK in sdb sdc sdd; do grub-install /dev/$DISK; done probably this is an issue when upgrading grub, too.
