is ambiguous; possibilities: \'--output\' \'--output-all\'\n\nUsage:\n lsblk [options] [<device> ...]\n\nOptions:\n -a, --all


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'.
