My last post about Solaris 11 triggered an interesting discussion with UX-admin about IPS and the lack of pre-/post-scripts for installation/removal.

Assuming that Solaris 11 will be based on IPS (no link, opensolaris.org no longer exists) just like OpenSolaris, it is certain that sysadmins will have to change a lot in how they create and manage packages, because IPS is fundamentally different from the good old System V packaging system.

So let’s explore the lack of scripting hooks in IPS and see if we can find some ways of working around them:

In the last couple of posts, we used DTrace to notify our media servers and perfected our script a bit.

But the script is still not ready to be used on our home servers yet: It requires manual start and stop, not quite the service oriented automatism we’re used to in the Oracle Solaris world.

The next step is to wrap our DTrace script inside a Service Management Facility (SMF) service, then wrap everything into a shell script that will easily install or remove the service whenever we need it.

During OSDevCon 2009 in Dresden (no link, osdevcon.org no longer exists), I had the honor to present on some lessons learned while putting together a ZFS Automatic-Scrubbing SMF service.

Today, Deirdre was so kind to publish the video recording of my presentation on The Oracle Solaris Video Blog (no link, sun.com no longer exists).

From the description:

This talk walks you through the implementation of a simple SMF service. What sounds "simple" at first, develops a life of its own when you consider installation/de-installation, security considerations, error handling and debugging, and of course unexpected little bugs and shortcomings. Finally, we add a GUI to our service by discovering the OpenSolaris Visual Panels project. This "lessons learned" talk is intended to be a practical roundup of things to consider for developers interested in integrating with SMF.
