grub-mkconfig depends on grub-install?

[Chris Murphy]

Does grub-mkconfig have any dependency on the things that grub-install or 
grub-mkimage produces? I'm thinking of the case where a user has an existing 
boot manager/loader, and they do not want a newer one replacing what they have. 
But perhaps they still need a grub.cfg: e.g. Install Ubuntu, using its 
installed GRUB2 and grub.cfg; subsequently installing Fedora to try out but 
user doesn't want Fedora's installer overwriting Ubuntu's boot manager 
experience.

Is it possible to run grub-mkconfig within a chrooted Fedora post-install, 
without first calling grub-install or grub-mkimage? Or should grub-mkimage be 
done before grub-mkconfig?


Thanks,
