Re: Fedora has a boot option that forces the installer to recognize a drive as GPT, can this be added to Debians installer?

Yes, but is it not sensible to leave it up to the user to partition it
with GPT themselves? Otherwise, you may have people who go to the
trouble of conducting an installation onto a GPT disk and finding out
at the very end of the process that the system is never going to be
able to boot.
