Wondering if anyone can comment on an easy way to get grub to update
all components in a raid1 array.  I have a raid1 /boot with a raid10
/root and have previously used lilo with the raid-extra-boot option to
install to boot sectors of all component devices.  With grub it
appears that you can only update non default devices via the command
line.  I like the ability to be able to type lilo and have all updated
in one hit.  Is there a way to do this with grub?  

assuming your /boot is made of hda1 and hdc1:

grub-install /dev/hda1
grub-install /dev/hdc1
