That reminds me.

Our DOS-type partition tables are close to their limit -
regularly people complain about things that do not work
with disks of size between 1 TB and 2 TB, and if not today
then very soon we'll see disks too large to handle with
DOS-type partition tables.

Two years ago or so I wrote some simple-minded stuff -
maybe there also was discussion on Linux-type partition tables,
I forgot all about it.
(Maybe the format was plan9-inspired, with sequence number,
start, size, label and uuid, all in ASCII.)

What is the situation today? What is the structure of these
LVM or raid partition tables? Is there some natural type
suitable for crossing the 2 TB limit?
Is it better to invent a Linux-type partition table?
