Puppet users - Nov 2013 - nodes.pp on puppetmaster vs. puppet agent on puppet client

If I change nodes.pp on the PM, do I have to do an /etc/init.d/puppet 
restart on the puppet client
to get it to receive the changes? I.e. does it have the old 
manifests/modules until the restart is done?

Hi Stuart, 
    You don''t have to do /etc/init.d/puppet restart on client machine, 
whenever "puppet agent" run/ fetches the catalog from PM using latest 
manifests. 


Thanks,

But it has to be activated in nodes
to fetch, no?

No. An agent need not be aware of what classes are assigned to it before it
contacts the puppetmaster. As long as your agent is configured to run on a
regular interval, it will automatically get the latest configuration on the very
next run. If you want to manually run the agent to apply those latest changes
immediately, you can use ''puppet agent -t'' instead of
restarting the service.

And there does not need to be any node block at all for an authenticated 
node in order for it to sync with the master.  If there isn''t one, and
if
there is no other way that any resources are declared for that node, then 
it will receive an empty catalog.  Node blocks associate declarations with 
specific clients (nodes) or groups thereof.  They are not a security 
mechanism -- that''s the role of cryptographic certificates and SSL.

Supposing the usual case in which nodes'' certificate requests are
handled
through the master, the certificate signing process must be completed, 
once, for each node before that node can successfully retrieve catalogs 
from the master.  Even that does not require the agent to be restarted if 
it is running in daemon mode, however.
