#includedir documentation reads:
    #includedir /etc/sudoers.d
    sudo will read each file in /etc/sudoers.d, skipping file
    names that end in ~ or contain a . character
=> the directive is enabled, but the files tails-greeter drops in
   sudoers.d/ are skipped since they have dots in their names.
