# Fact: systemd
#
# Purpose:
# Determine whether systemd is the init system on the node
#
# Resolution:
# Check if the service_provider fact is systemd
#
# Caveats:
# If you override the service provider then it will return false, even if the
# underlying system still is systemd.
#
# Fact: systemd_version
#
# Purpose:
# Determine the version of systemd installed
#
# Resolution:
# Check the output of systemctl --version
#
# Caveats:
#
# Fact: systemd_internal_services
#
# Purpose:
# List all systemd internal real services + their state
#
# Resolution:
# Check the output of systemctl --list-unit-files systemd-* and parse it into
# a hash with the status
#
# Caveats:
#
