# Fact: interfaces
#
# Purpose:
#   Returns a comma-separated list of the system's network interfaces.
#
#   In addition to the main `interfaces` fact, this code will generate the
#   following facts for each interface:
#
#   * `ipaddress_<INTERFACE>`
#   * `ipaddress6_<INTERFACE>`
#   * `macaddress_<INTERFACE>`
#   * `netmask_<INTERFACE>`
#   * `mtu_<INTERFACE>`
#
# Resolution:
#
# Caveats:
#

# interfaces.rb
# Try to get additional Facts about the machine's network interfaces
