Comment 21 for bug 61108

Lonnie, it's not that bad. The installer sets #groot correctly for most people. It's usually when you have raids, or a mix of ide/sata drives it guesses wrong. But I agree that it shouldn't do these poor guesses every time you install a new kernel.

It makes sense to have one #groot for all kernel installed on the same system (= same boot partition). #groot is what the grub loader is told at boot, to know where to find your kernels. Since your kernels are all on one partition, there's only one way to specify that partition -> one #groot.

For more discussion, I suggest you write up a proposal on a wiki page, and work towards a specification. OTOH, grub is so system critical, that Ubuntu is probably not going to deviate far from Debian, and it should get fixed there first. However, grub developers are more interested in grub2 than reworking the old, crufted grub.
