I definitely agree with the "annoying" description, which is why I no
longer use these tools.

However, the new setup has a certain theoretical elegance (even if it
is doubly annoying that there are files in both /etc/default and
/etc/grub.d to edit in order to customize your grub.cfg).

Although in practice it is exactly like lilo (I have been playing with
grub2 since late September/early October and have forgotten more than
once to run update-grub before rebooting), update-grub generates a
"normal" file whereas lilo used to update (to lilo fans with
apologies: I am using the past tense because I have not used lilo in
ages) the MBR or at least the pre-63rd block of the disk (if I
remember correctly).

The problem is not upstart. It is Ubuntu's choice, for its desktop
edition, to have init levels 2-5 be exactly the same.

I have forgotten whether the previous version of Ubuntu had an inittab
but the current one, 9.10, does not. You can nonetheless modify the
init levels at which init scripts are run (or not) and pass an init
level as a kernel parameter in grub or through "init X".
