Bug#815569: partman-md: it should be able to choose metadata={0, 1, ddf, imsm} when creating the RAID

Package: partman-md

Severity: normal

Dear Maintainer,

I'm porting d-i onto a few Buffalo Linkstation NAS devices recently.
Linkstation's u-boot loader loads kernel/initrd from 1st partition of the disks,
which only recognize metadata=0 (or so-called 0.90) for RAID-1 case.

But as you know currently partman-md can only create metadata=1.2, so
I have to type:
  mdadm --create /dev/md0 --level=1 --raid-devices=2 -e 0 /dev/sda1 /dev/sdb1
to create the /dev/md0 manually.
BTW. partman-md can create the rest /dev/md1, /etc/md2, etc, without problem.

So I ask you to support specify the metadata style when creating the RAID.
Thank you!

Cheers,
