#
# 1. Workaround for issue #16277 where default settings aren't initialised from
# a spec and so the libdir is never initialised (3.0.x)
# 2. Workaround for 2.7.20 that now only loads types for the current node
# environment (#13858) so Puppet[:modulepath] seems to get ignored
# 3. Workaround for 3.5 where context hasn't been configured yet,
# ticket https://tickets.puppetlabs.com/browse/MODULES-823
