I agree with Steve comment but the point you guys are missing here it's a multi-tenant system and I'm getting hard time to visualize how a custom fact will handle the situation as the the same command will return different result for different databases, based on the client.
It does make difference in the sense as /etc/passwd is unique for given puppet agent but it's not when you running, e.g. ls ~/Documents|wc -l for different users on the same puppet agent. How you will do the with a custom fact? I'm glad to be educated. -S On Monday, February 1, 2016 at 2:31:08 PM UTC, jcbollinger wrote: > > > > On Friday, January 29, 2016 at 12:43:17 PM UTC-6, Sans wrote: >> >> >> Steve, how you doing??
