Still using ssh in a for loop to manage server clusters? Rewriting the entire hard drive of hundreds of workstations just to tweak one setting? Managing your systems by hand? Having trouble keeping up with all the changes to all the systems? Maybe it's time to try something new.

Puppet is a system for automating system administration tasks. Puppet is also a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration.

Huh? In other words, you edit files in a nice readable language and magically the right things change in the right order on all the right systems. It's like your systems configure themselves.

In the beginning there were only the mainframes. Administration only
required configuration of one system. Users accessed the mainframe from
dumb terminals. Everyone had access to the same resources and had the same
software, because everyone was on the same system. Then came the personal
computer. Users all got their own systems, and system administration
became exponentially more difficult. LTSP gives us a way to get the
terminal server, singular administration and control we admins want and
still give users the warm fuzzy interface, speed and freedom they want.
One system, one set of updates, one place to make changes. We're going to
look in to some of the history of LTSP, overview the technology involved,
and some of the many potential applications. Finally we'll look at the
best way to implement LTSP, and how its working in production in our
corporate environment.

While you might not be able to tell at a cursory glance, a lot has changed behind the scenes on a modern Ubuntu system from what you might be used to if you have used Linux for years. For example, did you know Ubuntu is phasing out System V init? That you can't loopback-mount the initrd? In this talk I would discuss the current changes Ubuntu is making to what we might consider the traditional Linux system. There's a little something for everyone on the talk: For Linux newbies who are curious about what's under the hood I will cover the traditional and modern boot process including how init works and follow up with a guide to where important files are in Ubuntu. For the experienced Linux user I'll show you how (and why) things have changed and where you can look now when you want to, for instance, change the default runlevel on an Ubuntu system.
