It's update-grub (actually grub-mkconfig) not grub-install which
replaces it.

Maybe you missed the big warning at the top of the generated grub.cfg
that you should not modify it directly?

User config files belong in /etc according to Debian Policy and also FHS
and must preserve user changes.
I think because of this some distros have a /etc/grub.conf symlink
to /boot/grub/menu.lst
GRUB Legacy's configuration for update-grub was just weird and violated
this, so it got replaced with a more cleaner version.

We have already an open report to make a backup #538743.
