Thanks for your reply!
My issue was that my dnsmasq class was a) downloading the package b)
setting up the service and c) adding monit monitoring scripts for it. The
last part was the cyclic dependency issue. A number of things are
monitored by monit, and pulling one of them into my 'preload' stage
involved pulling all the other dependencies, too, which didn't work.
My solution was to split up the dnsmasq class, separating the package
download (and initial run) from the rest. I then added this into its own
special stage (preload->dnsmasq->main), which solved my problem. I hope
this helps future travellers.
Best,
Matt

I've got a manifest that involves downloading and updating a bunch of
different packages using apt, pip, etc. One of my apt-dependencies,
dnsmasq <
http://www.thekelleys.org.uk/dnsmasq/doc.html>, redirects the
machine's DNS. Any modules currently running at that time that use the
internet get a temporary name resolution error. Unfortunately, I can't
run this class in a different stage, as it creates a dependency cycle
with the other things that depend on dnsmasq.
Is there a way to force puppet to run a particular class by itself?
There are enough other tasks/jobs/whatever-we-call-them that being
explicit about the dependencies isn't really worth it (and it'd have to
be kept up to date as my manifest grows).
You might want to look into tags. I've got a few resources which are
applied to bootstrap the whole process, which can be applied separately
using "--tags kickstart::bootstrap", which is used while kickstarting
the node. This ensures that when it reboots, it has a properly
configured puppet, but doesn't start services in kickstart.
Alternatively you can pack the initial installation and configuration of
dnsmasq into an exec{} to ensure semi-atomic execution. Not recommended,
but possible.
