# Fact: fqdn
#
# Purpose: Returns the fully qualified domain name of the host.
#
# Resolution: Simply joins the hostname fact with the domain name fact.
#
# Caveats: No attempt is made to check that the two facts are accurate or that
# the two facts go together. At no point is there any DNS resolution made
# either.
