Raid 1

I was trying to get the whole lvm array on md0, but was having issues.
Got this working and really aren't worried about 2 software raid devices.

Perhaps I wasn't as clear as I could have been. But in my preseed, the
defined partitions are always getting created using the minimum allowable
space. The remainder of space ends up getting added to the dummy lvm
volume. I thought the remainder of space would get distributed between the
defined partitions based on their priorities, with any remaining going to
the dummy partition.

The partitions created were sized at their minimum values, and the dummy
lvm volume was many hundreds of GB.

Max sized defined partitions with whatever is left over in the dummy lvm
volume

Probably could have chosen a better subject.
I read on a blog somewhere that the priorities were actually from low
numbers to high. First I had read that, but adjusted preseed to the
following.
