env_reset If set, sudo will reset the environment to only contain the LOGNAME, SHELL, USER, USERNAME and the SUDO_* variables. Any variables in the caller’s environment that match the `env_keep` and `env_check` lists are then added. The default contents of the `env_keep` and `env_check` lists are displayed when sudo is run by root with the -V option. If the secure_path option is set, its value will be used for the PATH environment variable. This flag is on by default.
