# 4. Replace OpenJDK's built-in CA certificate keystore with the one from the OS
# vendor. The latter is superior in several ways.
# REF: https://github.com/elastic/elasticsearch-docker/issues/171
# 5. Tighten up permissions on the ES home dir (the permissions of the contents are handled earlier)
# 6. You can't install plugins that include configuration when running as `elasticsearch` and the `config`
# dir is owned by `root`, because the installed tries to manipulate the permissions on the plugin's
