[Maas-devel] curtin custom partitions

[Newell Jensen]

Kyle,

Looks like me email updated me with your new email after I sent
mine...weird.

In any event, the default partition function that is called in that shell
script is pt_gpt, not pt_mbr.  The reason there is a cap on pt_mbr is due
to the size limitation that MBR has:

"The organization of the partition table in the MBR limits the maximum
addressable storage space of a disk to 2 TB
<http://en.wikipedia.org/wiki/Tebibyte> (232 × 512 bytes)."
