Image Packaging System (IPS) is a new package manager Sun has developed for OpenSolaris. While I have my doubts about whether a brand-new package manager was a good way of spending engineering resources, OpenSolaris had a number of very nice features that made it a convincing platform to run Jenkins, thanks to SMF, ZFS, and zones. So I used to produce IPS packages for Jenkins. I lost the ability to do this as I left Oracle and lost access to a Solaris system, but a recent blog post renewed my interest.
So I'm happy to announce that the Jenkins project has started producing IPS packages for the releases. With this addition, the Jenkins project now produces 9 packages on different platforms (10, if you count Ruby as a separate platform :-)
