We should probably have olpc-update check /etc/redhat-release for the
string 'OLPC release' and bail out if it isn't found with a message
like 'This is not an official OLPC release, cannot update.  Please use
your distributions package manager'.   This should allow the utility
to live in a distro's eco-system but not cause complete confusion if
it is installed and run on non-OLPC builds.
