Not *exactly* true.

Grub can chainload any bootloader that's visible to BIOS. At minimum,
that means you could have grub on /dev/sda chainload grub on /dev/sdb.
I'm uncertain if it means you could chainload a bootloader stored in
the first 512 bytes of /dev/sda8, but I suspect so.

So do most distros I've touched. Just an FYI.

I think your instructions will work fine for him, though. I was going
to offer some grub1 stanzas, but I wasn't sure if real_root was
necessary.
