You are both correct?

There are good reasons to have different bootloaders on different disks
(MBRs, partitions, whatever) but there are also good reasons to copy the
same bootloader to different devices.

In my opinion, fai should be able to support both options. I don't mind
the  default behaviour, as long as I'm able to change it to my needs.


Use cases that come to mind:

- single disk / single os
- multiple disk / single os -> raid configuration
- multiple disk / single os -> separate system and data disk
- multiple disks / multiple os -> OS select via grub
- multiple disks / multiple os -> OS select via bios
- no bootloader at all

Also chosing between installing the bootloader in the mbr or in a
partition is a nice feature to keep.
