Yes, of course. The point you seem to be missing is that until the
package is upgraded, those won't exist, and until they exist, I can't
upgrade the package.

If you have more specific suggestions, I welcome them. Telling me what
I don't have to do is really not helpful. Note I am not particularly
intersted in completely over-writing GRUB legacy until I know GRUB 2 is
working: I very much like the Debian upgrade approach of chain-loading
GRUB2 from GRUB legacy until one is certain everything is working. I'm
running Debian "Squeeze", upgraded from "Lenny". I have a RAID1 array
which is mounted as /boot once the system exits initrd. GRUB legacy
reads one or the other RAID1 member as if it were an ordinary partition
and boots accordingly.
