** Description changed:
+ === Begin SRU Information ===
+ [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'}}
+ }
+
+ === End SRU Information ===

-
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'.
