# Fact: ldom
#
# Purpose:
#   Returns a list of dynamic facts that describe the attributes of
#   a Solaris logical domain. The facts returned will include: domainrole,
#   domainname, domainuuid, domaincontrol, and domainchassis.
#
# Resolution:
#   Uses the output of `virtinfo -ap`.
#

  # DOMAINCONTROL|name=san-t2k-6
  # DOMAINCHASSIS|serialno=0704RB0280
  #
  # For keys containing multiple value such as domain role:
  # ldom_{key}_{subkey} = value
  # Otherwise the fact will simply be:
  # ldom_{key} = value
