# Fact: hostname
#
# Purpose: Return the system's short hostname.
#
# Resolution:
#   On all systems but Darwin, parses the output of the `hostname` system command
#   to everything before the first period.
#   On Darwin, uses the system configuration util to get the LocalHostName
#   variable.
#
# Caveats:
#
