# virt-install maintainers and they said the point of that message
# is that you can't absolutely depend on the output not changing, but
# at the moment it's the only option for us. Long term plans are for
# virt-install to switch to libosinfo for OS metadata tracking, which
# provides a library and tools for querying valid OS values. Until
# that's available and pervasive the best we can do is to use the
# module if it's availabe and if not parse the command output.
