this is also a pain on many systems.  for example my own.  even if i set
a sata drive as the first boot device in my bios, grub/linux always sees
my pata drive first and installs grub there.  my pata drive is a
removable drive in a cage which holds vmware images.  to get around the
problem i have set my bios to use the pata drive first and grub is
installed there.  should i remove the pata drive, the bios and linux
then put my primary sata drive as the boot device and thus i have
installed grub to that mbr as well.

the /dev/sd* names change but ubuntu is smart enough to use UUIDs so
everything handles the changes just fine.
