However, I don't even know if it would be possible to boot from multiple devices, since I think this may even be a BIOS thing to load the blocks, otherwise we would never be restricted to BIOS devices for boot... > It just does not make much sense then, because with a DOS partition table > you can as well have a partition based /boot It's still not good to have a partition-based /boot, because you can't migrate it, enlarge it, etc (carefully, mind you). There are still some limitations for LVM based /boot, but if you have /dev/hda1 that is all in LVM, you are free to manage it any way you want. The partition table is only a few kB... You can make all your other disks full LVM disks and save a few more kB, if you are TOTALLY SURE you will never want to boot from any of them... Cheers, Andreas
