I don't envision a GPT flag day. Mainly as using GPT isn't as incompatible=
=20
and irriversible a thing as "Flag day" implies.

We are moving (ever so slowly at times) towards wedges. We will flip the
switch on them at some point, and not go back. However we have wedge
readers for MBR and raw disklabel disks too. So wedges aren't going to
trigger a GPT flag day AFAICT. And wedges do work in 4.0, even though they=
=20
aren't default.

Yes, I envision a day after which our tools will default to GPT. But I
expect there will be some backwards compat available. Like a tool to make
an MBR for boot partitions or a disklabel for boot partitions. I forsee
limits on such GPT boot partitions, since you'll need to be able to
express them in terms of the compat format (either MBR or disklabel).

Take care,

Bill
