default to msdos disk labels?

Umm. Reality check please from someone who understands this. This reads to me like 'nogpt' is going away, MBR is returning by default, and if we want GPT on BIOS to use 'gpt' to force it.

Am I reading this wrong?

It does appear that GPT will not be used by default on all systems according to that.

It does indeed appear that if you have a BIOS system, then it won't default to using GPT unless you tell it to.

I don't read code, but I'd like to think it will default to GPT if the disk size is larger than 2.2TB, even if it's a BIOS system.

Well, I would assume that if it doesn't, then you could specify the 'gpt' option to force it to use gpt.

But, I would hope that it would automatically default to GPT if the drive size was larger than 2TiB - 512 bytes.

Yeah I'm not clear on any of the implications of 4Kn disks appearing on the scene.

Appears confirmed.

So, it appears that it will now be done the way that it should be done.
