Comment 6 for bug 1314686

We do need the actual series name and version number in the code. The reason is that there's validation to ensure that simplestreams metadata for images and tools is correct, and we need to check that the series information encoded in the metadata is correct. We read the series info from /usr/share/distro-info/ubuntu.csv. However, we can't guarantee that the distro-info-data package is installed, so use hard coded fallbacks just in case. I guess a question I have is do we really care about running Juju 1.18 on Utopic given that by the time Utopic is released, there will be a matching Juju version also. We've got some other 1.18 bugs to fix so we are also able to easily add Utopic support anyway in this case, but in general, I wonder what our policy will be?
