Comment 32 for bug 1432871

Perhaps it was reverted? This actually works fine for me on trusty in the older 8.21-1ubuntu5.1 but not the newer 8.21-1ubuntu5.3 or 8.21-1ubuntu5.4 I ran into the problem with it outputting UUID because amazon's aws ec2 cloudwatch script mon-put-instance-data.pl uses it as its Filesystem dimension and my alarms all of a sudden had insufficient data after apt-get upgrade:
