Anything else, such as using NFS for either of those, would open root
security vulnerabilities.

If you are asking how you can distribute your sudoers file to a
cluster of machines that is a different question.  There are many
different schools of thought.  I highly recommend reading this paper:


What works best for you depends much upon how large of an
infrastructure you are supporting and the skill level of those doing
the support.  Some use cfengine.  Some use CVSup.  Some use radmin.

Personally I use a cron task on each machine that pulls the file using
ssh and rsync from a trusted server with a skewed time so that they
don't all go off at once.  I only have a small network, around twenty
five hundred heterogeneous hosts to synchronize, so this works quite
