# A Facter plugin that loads facts from /etc/facter/facts.d
|
||||
# and /etc/puppetlabs/facter/facts.d.
|
||||
#
|
||||
# Facts can be in the form of JSON, YAML or Text files
|
||||
# and any executable that returns key=value pairs.
|
||||
#
|
||||
# In the case of scripts you can also create a file that
|
||||
# contains a cache TTL. For foo.sh store the ttl as just
|
||||
# a number in foo.sh.ttl
|
||||
#
|
||||
# The cache is stored in /tmp/facts_cache.yaml as a mode
|
||||
# 600 file and will have the end result of not calling your
|
||||
# fact scripts more often than is needed
