The ^right^ way to do this ofcourse is to have centralized sudo rather than
copying the sudoers file to every machine:


If you think that is more effort than warranted for your use case, I would
suggest going with scp (if you are ok with overwriting, that is) every time you
update sudoers, basically:

$ export SYSTEMS=""
$ visudo && for i in $SYSTEMS; do scp /etc/sudoers root@$i:/etc/ ; done

If having the same sudoers file on all system is all that you need, this ought
to suffice
