grub-install does not override config

[[mrs_sheep]]

I played around with my grub-configuration ( /etc/grub.d/ ) - very stupid, I know - and broke it completely. See here, "alloc magic is broken" http://askubuntu.com/questions/183601/cant-boot-no-grub-alloc-magic-is-broken.

I then started to reinstall grub from a live CD (more or less with sudo grub-install --root-directory=/mnt /dev/sda ).

This did not change anything and after playing around a while I checked the grub.conf and saw that the old error still remained.
It turned out that though reinstalling it would use the old configuration (the broken one.)

I'd suggest grub-install to ask the user whether to override or to back it up. (and .bak to the files does NOT work)

This is by design; it is update-grub, not grub-install that is responsible for generating the config file.
