Could allow chchi installer to present as one of the initial choices to enter to the “grub>” prompt?
That would be helpful in cases when the system will not boot anymore, since the system could be made to boot with just a couple of very simple commands, even without chroot (which is confusing to many people).
These commands could be given under the “grub>” prompt:
search.file /etc/pacman.d/antergos-mirrorlist root configfile /boot/grub/grub.cfg
and it then boots to Antergos again, and then fixing the boot issues would be much easier.
