# We assume 0-init/tasks/validate_vars.yml has DEFINITELY been run, so no need
# to re-check whether vars are defined here.  As Ansible vars cannot be unset:

  # 2020-02-11: @mitra42 & @holta agree (#2247) that the following 2-stanza
  # "UPDATE internetarchive" portion should run whenever one isn't installing
  # (or reinstalling) internetarchive, for now.  We're aware this means slowness
  # during "./runrole internetarchive" but that's very intentional for now -- as
  # it leads to more testing of more recent versions of internetarchive, which
  # is strongly desired.  Finally, these current norms can and probably will be
  # changed in future, when broader IIAB norms develop around "./runrole
  # --upgrade internetarchive" or "./runrole --update internetarchive" or such,
  # as may evolve @ https://github.com/iiab/iiab/pull/2238#discussion_r376168178
