-- | Specifies the user and group whose permissions are used when running the

-- absolutely necessary to minimize the risk of unintended changes or
-- malicious attacks. To run as root, you must set \'\'IsolationMode\'\' to
-- \'\'NoContainer\'\' and update config.json in
-- \'\'greengrass-root\/config\'\' to set \'\'allowFunctionsToRunAsRoot\'\'
-- to \'\'yes\'\'.
