kickstart using GPT... without EFI

[Jonathan Smith]

We have an x86_64 system with >2tb drives which does not have EFI. However, the BIOS will boot GPT if present.

Unfortunately, anaconda seems to only use GPT if (U)EFI is present. I've tried creating the GPT label in a ks %pre[1][2], but it didn't help... anaconda always overwrites it, even though I don't have a clearpart in my ks.

I can successfully convert it after-the-fact, but I'd prefer that it be done correctly by kickstart.

Suggestions?
