Package: debian-installer
Severity: normal
Partman opts for GPT when installing on a disk larger than 2 TB (2 * 10^12 B),
even though the limit for DOS partition map is 2 TiB (2^32 * 512 B).
This can be easily reproduced with qemu:
qemu-img create -f qcow test.img 2047G

I don't think the difference is big enough to worry about it. As IMO this is
not a "bug", I'm closing the report.
And I don't think we have any "hard" reasons to prefer one over the other.
It's mostly that people are used to dos, but if anyone were to make a solid
case for switching to gpt by default I would have no problems with that.
I personally don't know enough about either to be honest.
Cheers,
FJP
