Description of problem:
After installing /boot and / on a software Raid1 device, I recognized, that grub
is only installed on one of the disks of the raid array.
I one disk fails, the system won't boot any more

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Install /boot and / on a software raid1 system (2 disks)
2.halt system and plug out one disk
3.try to reboot

Actual Results:  system doesn't boot any more

Expected Results:  system should boot from second disk

Additional info:

It is possible to install it manually on both disks by entering the following
commands (in my case).
But grub should do this automatically or ther should be a note, that the
bootloades is only installed on one disk.
Otherwise the redundancy of a raid 1 system is not reached

device (hd0) /dev/hda
root (hd0,1)
install /grub/stage1 <*> (hd0) /grub/e2fs_stage1_5 /grub/stage2 /grub/grub.conf
device (hd0) /dev/hdb
root (hd0,1)
install /grub/stage1 <*> (hd0) /grub/e2fs_stage1_5 /grub/stage2 /grub/grub.conf
