Regarding that fqdn and uptime_seconds are facts, that is understood.
The agent node updating the file and triggered the content change may be
obvious to you, but I'm a puppet beginner, and I yet don't have a solid
understanding of the catalog run or how, when or where the tags get
updated.
1. I thought that the file on the agent node would never be updated
unless the content on the puppet master changed which would trigger the
catalog run and force the update.
2. Instead, it appears that the agent node will trigger an update per
it's runinterval, resolve the dynamic tags and if a fact needs updating,
it will update the corresponding file and generate the content changed
message I saw in the the agent node log.
Is this close to correct?
Meanwhile I'm going through ProPuppet and everything I can find on the
puppetlabs site and hope to have a better understanding.
I think the glue that you're missing is that, while the template on the
puppetmaster has not changed, the value of the variable in the template
has changed.
Variables in templates can come from many places in puppet. In this
particular case, you (or someone) has used a fact. Facts values are
filled in by the agent on the node at the start of a run, before
catalogue compliation, so that they are available to the master for use
in the catalogue.
http://docs.puppetlabs.com/guides/custom_facts.html may be of some help
to you.
