basically, util-linux's lsblk gained a '--output-all' argument, which made our use of '--out' ambiguous. Note, back to 12.04 supports --output per http://manpages.ubuntu.com/manpages/precise/en/man8/lsblk.8.html .
not sure why I used '--out'. |

[Impact]
curtin install if util-linux is at utopic version or later.
The problem is that curtin's '_lsblock' which is used to get invoke lsblock to
get information about the block devices of the system used '--out=' to specify
the output format rather than '--output'. In utopic the version of util-linux
contains a lsblock with '--output-all' flag, which made '--output' ambiguous
and the command would fail.
The fix is then straight forward and is to just use '--output=' rather than
'--out='. I'm not sure where the usage of '--out' came from as versions
of util-linux back to 12.04 support '--output'.
[Test Case]
$ sudo apt-get update -qy && apt-get install -qy python-curtin
$ dpkg-query --show python-curtin util-linux
python-curtin 0.1.0~bzr190-0ubuntu1
util-linux 2.25.1-3ubuntu4
$ python -c 'from curtin import block; import pprint; pprint.pprint(block._lsblock())'
Result currently is stack trace on utopic.
Success is a pretty printed dictionary of 'lsblk' information like:
{
'vdb1': {'ALIGNMENT': '0',
'DISC-ALN': '0',
'DISC-GRAN': '0',
..
'UUID': '',
'device_path': '/dev/vdb1'}}
}
