Description of problem:
Hi!
Recently i play a bit with harddrives, with RAID/lvm configurations /on my home pc/.
When i choose 2 /or more/ partitions /each the same size on seperate hdd/, and create raid1 /mirror/ partition that will serve me as /boot, than i set-up other raidpartitions/lvms, after i click "next" anaconda asks me what is default text in grub, and where grub is going to be installed. default it's /dev/sda- which isn't the best choice in situation, when /boot is installed on raid device made from mirrored partitions (so: /dev/md0 is de facto /dev/sda1, /dev/sdb1, /dev/sdc1). default localization should be set on /dev/md0, which was, during creation, selected to be mounted as /boot
