it will automatically be enabled for future runs. Do NOT use this option
if you have already started to customize your configuration.
``--sudo``: Audit your system as a normal user, but allow sudo escalation to read
specific root read-only files. You need to provide a sudoers file in /etc/sudoers.d/
with NOPASWD option, since checks are executed with ``sudo -n`` option, that will
not prompt for a password.

This option lets you audit your system as a normal user, but allows sudo
escalation to gain read-only access to root files. Note that you need to
provide a sudoers file with NOPASSWD option in /etc/sudoers.d/ because
the '-n' option instructs sudo not to prompt for a password.
Finally note that '--sudo' mode only works for audit mode.
