So that means that grub-install would need to read some other file maybe /etc/default/grub-install to know if it has to ignore stage1_5 or not. Then I add a --ignore-stage1_5 option to setup command and that's it.

I think that /etc/default/grub-install should be sourced from grub-install at its first line and that would be fine.

Do you have any more ideas till I actually code this, well, finish coding it?
