Talk I gave at puppetconf2013 on using exported resources to dynamically configure your system. Using augeas and concat the examples build up a working dns implementation that is automatic. The system was simplified a lot for the talk but the principles of using exported resources to configure the system is powerful.
I knew this script looked familiar, I just wrote the same script as I wrote almost a year ago. I guess I didn't do a good job getting it on the google's, cause I couldn't find it until I started posting about it...github:pass_to_shadow.py
Maybe this time I'll include some of the code in this post.

This has come up 3 times in the last few days so I thought I'd share it. The situation is that there are files at /var/spool/mqueue that are part of the /var filesystem. But there is also another filesystem mounted at /var/spool/mqueue with it's own files. You want to access the files under the mount but you can't. So, there are two ways around this (in this instance).
The scenario is that users are controlled by sssd and you want to add a user locally for those times when your connection to your password backend goes down. Useradd won't let you do it though, cause the user already exists. I figured augeas would be the perfect way to do that but I kept hitting a problem, augeas would fail.
I was trying to get my Samsung TV to play files from my Beefy miracle box and although it was able to connect, it would not show any files. It took a bit of hunting around but I found the following patch needed to be applied to get the files to display.
diff -ruN mediatomb.orig/tombupnp/upnp/src/genlib/net/uri/uri.c mediatomb/tombupnp/upnp/src/genlib/net/uri/uri.c
A talk I gave at Lopsa NJ on linux-kvm, slides in a google doc here
John recorded the talk so maybe it'll be posted on lopsa's website soon...
The latest version of skype doesn't appear to work well on RHEL6, I found the following forum http://community.skype.com/t5/Linux/Skype-for-Redhat-Enterprise-6/td-p/… and followed the two things mentioned there to make it work.
I wanted to be able to define nfs shares with puppet and have puppet take care of the exports line and exportfs. I found this page, but I didn't like that there was perl code thrown in the midst. I rewrote it to use an inline template instead.
The code is up on github at github.com/uphillian/puppet-nfsshare
