To be clear frack uses essentially the same apt module as production, and
this seems to be the behavior of the production puppet as well. Point
being we should be able to significantly reduce the pain of production
puppet runs with a fairly minor change.

On a related note, I've been looking at puppet agent run time in frack and
I noticed that puppet executes apt-get update literally every run, and
this accounts for a large chunk of the agent run time.
Seems like it would be reasonable to reduce the apt update frequency to
once or twice per day, and maybe even to handle it by splayed cron job
instead of as a puppet exec.

Puppet is very resource intensive and runs every 20 minutes are a
waste of resources even in prod, probably; it is surely taking a
not-so-small toll on labs in term of cpu/iowait spikes.
+1 to Antoine's proposal.

Hello,
I noticed labs instance run puppet every 20 minutes just like
Wikimedia production. I thought on labs it could be run just
once per hour which would slightly reduce load.
That wouldn't necessarily be bad, but can you explain what problem
you're hoping to fix? As far as I know, virt1000 (the labs
puppetmaster) doesn't have any complaints about load.
