Thanks for the advice Mark and Rashkae. I guess now I actually have a 
valid reason for having a separate partition for /boot. Would you 
recommend setting the bootable flag for /boot partition on each drive or 
just one of them?

To be or not to be, that is the question
                2b || !2b
(0b10)*(0b1100010) || !(0b10)*(0b1100010)
        0b11000100 || !0b11000100
        0b11000100 || 0b00111011
               0b11111111
        255, that is the answer.
