Title:
Upon RAID partitioning I get "Duplicate key in mdadm regex parsing:
UUID"
Status in curtin:
Expired
Bug description:
I'm trying to install Ubuntu 18.04 with curtin under MaaS 2.4 control
on a RAID1 array.
Apparently, under the hood curtin runs
`mdadm --examine /dev/md127`
Which in turn calls __mdadm_detail_to_dict(input):
https://github.com/CanonicalLtd/curtin/blob/f02fd6132b770149b02644018fd65319a77c8338/curtin/block/mdadm.py#L605
Here's the output of my `$ sudo mdadm --examin /dev/md127` command:
$ sudo mdadm --examine /dev/md127

As you can see, there's indeed a duplication of key 'UUID', as there
are two UUID fields in my mdadm result, one for the whole Raid
controller, and the other just for one volume. Those are different
sections, having different UUIDs with different meanings.
curtin crashes at this place and installation fails with the following
log:
```
curtin: Installation started. (19.1-7-g37a7a0f4-0ubuntu1~18.04.1)
Duplicate key in mdadm regex parsing: uuid
curtin: Installation failed with exception: Unexpected error while
running command.
Command: ['curtin', 'block-meta', 'custom']
Exit code: 3
Reason: -
Stdout: Duplicate key in mdadm regex parsing: uuid
Stderr: ''
