Bug Description

get_unused_blockdev_info works by using lsblk and looking at MOUNTPOINT.

That does not always work right on trusty.
example:
$ sudo mount /dev/vdb1 /mnt
$ sudo PYTHONPATH=$PWD python -c 'from curtin import block; print(block.get_unused_blockdev_info())'
{'vdb': {'GROUP': 'disk', 'OPT-IO': '0', 'DISC-MAX': '0', 'LABEL': '', 'MODEL': '', 'RQ-SIZE': '128', 'MODE': 'brw-rw----', 'ROTA': '1', 'RM': '0', 'RO': '0', 'device_path': '/dev/vdb', 'DISC-ZERO': '0', 'UUID': '', 'STATE': '', 'MOUNTPOINT': '', 'FSTYPE': '', 'SIZE': '42949672960', 'MAJ:MIN': '253:16', 'DISC-GRAN': '0', 'NAME': 'vdb', 'LOG-SEC': '512', 'DISC-ALN': '0', 'ALIGNMENT': '0', 'MIN-IO': '512', 'OWNER': 'root', 'KNAME': 'vdb', 'TYPE': 'disk', 'PHY-SEC': '512'}}

Note, this works correctly on wily, lsblk does thh right thing.

What does lsblk -o MOUNTPOINT /dev/vdb1 show?

I doubt that recent failure is the same thing, this looks like a race with, well, something else. Possibly the blockdev --rereadpt call should be protected with flock.

```

The installer encounters an error and along with the rest of the output, prints a note about this bug.  I was able to get past it by entering the installer shell, adding zeros over the disk well past the beginning of the md device partition, and restarting the PXE install after which time I did not re-encounter this bug.  I was re-purposing some systems and consistently hit it with both disks and 2 systems in a row which had a previous MD device setup on the disks, and dding zeros over it to wipe all the partitioning data out got me past it.
