[Labs-l] Slowing down puppet runs?

Fri Oct 31 16:35:02 UTC 2014

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.
