The grub.conf that is actually used is /boot/grub/grub.conf.  What you
see in /etc is a symlink so you have an easy time finding it to edit.
There are various ways that the symlink can be broken, so make sure you
really have what you expect under /boot/grub.  Also, depending on
how your system handles drive failure, you may or may not want the
same thing there.  Scsi systems normally move the first working
drive up to /dev/sda (and shift everything else up so non-labeled
partitions may be off).  Ide controllers often hang until you remove
the bad drive and then the system doesn't shift the names unless you
move the working drive to the primary partition.
