I don't have that file, and it's not because Gentoo removes it: it was
probably added by the Ubuntu developers.

But it's not part of GRUB2. If you had checked the project sources, or
the Gentoo ebuild, you would have realized that it is not a file from
the project.

That's the problem: you didn't know how the thing worked, and jumped
to conclusions.

You said that, but your next sentence was "It's got it's own init
system and it's own set of init scripts", unequivocally.

Maybe in Ubunt (and maybe not: distros this days throw every kind of
scripts in /etc/init.d, and Gentoo does this too, BTW), but again you
only took a quick look at how it's set in another distro, and jumped
to say that the project as a whole (and not the config from a
particular distro) "got it's own init system and it's own set of init
scripts". To me, that's the definition of spreading disinformation:
not looking for all the info, and stating that such and such is or is
not when it's simply not true.

It's the same history as the myth that /var will not longer be able to
be on its own partition: it keeps popping up in many threads, and it's
also simply not true.

Again, I don't think you did it on purpose with the intention of smear
GRUB2 (that was my "with the best of intentions" part), but *it is*
disinformation.

To finish: GRUB2 does not need or have init scripts, it doesn't have
it's own init system, and if your setup works with GRUB, it will work
in GRUB2, but you will probably need to learn a new way to configure
it. The other way around is not true: GRUB will not support all the
setups that GRUB2 will, unless someone steps up and writes the code
for it.
