You don't have to be so nasty you know. There is no right way to do
anything. I prefer not to touch my kernel (boot) configuration for
whatever reason I might have for that. I'm not sure what happens if I
could not depend on the current "grub" installation. Or what happens if
I need to boot from some other place. I prefer for the system to be
stable regardless of the boot loader. For instance, you can imagine
(re)booting into the current system using kexec. I know I am making an
ass of myself. But that is stuff I do. Or could want to do if it
actually worked for me.

Dependency on a boot loader that is in itself one of the most unreliable
pieces of software I have ever come across, is not really my favourite
thing I must say. I'm sorry if that sounds off.

I just wanted an on-disk configuration that is based on the system and
not on the bootloader, and it was possible before, and I didn't realize
why it was not possible now.

Editing /etc/default/grub is not really, you know.

On one occasion I have had a system where I could not use update-grub
because it didn't work, and I maintained a custom grub.cfg. Easy enough
to edit that as well, but Grub is not my piece of cake.

I'm sorry if that makes me sound like some idiot loser. I try to reduce
dependencies in my systems on stuff I find to be unreliable.

So if I can do this using some on-disk configuration file (or even a
symlink) that's better for me. Yes and I KNOW /etc/default/grub is also
on-disk. Don't mince words here, I mean, a regular config file.

That ideally gets used immediately, but whatever.

I just want to thank Martin Pitt for not being an ass about it (that I
might be myself, I don't know).
