sudo
sudo.d(directory):
Note also, that becasuse sudoers contents can vary widely, no attempt is made to add this
directive to existing sudoers files on upgrade. Feel free to add the above directive to the
end of your /etc/sudoers file to enabe this functionality for existing installations if you
wish! Sudo versions older than the one in Debian 11(bullseye) require the directive will only
support the old syntax #includedir, and the current sudo will happily accept both @includedir
and #includedir
