I can't test it (now.  Perhaps it is possibly in the future, but I really
don't know when).

According the docu, the default value is to save to Root partition and
not to save to MBR...  It is also not documented (not that I'm aware of)
that in a RAID configuration the MBR is written to both disks...

Is this GUI wise:

Install bootloader at:
[x] sda
[x] sdb
[x] sd...., etc when there are more disks

Not easy to understand from a user point of view....

Allow multiple disk selection when applicable.
