OpenIndiana 2025.10 released

OpenIndiana, the Illumos distribution for general use, has released its latest snapshot release, and there’s some really interesting things in there. To refresh your memory: Illumos is a fork of the final OpenSolaris release, based on Solaris 11, before Oracle closed Solaris back up. It’s been in development ever since that fateful day back in 2010, and several Illumos distributions with unique identities have sprung up around the project. OpenIndiana is one of them, and functions like a rolling release with a snapshot release every six months.

OpenIndiana 2025.10 was released today, and this snapshot’s changelog covers changes over the past six months. It comes with all the latest open source packages you would expect, like the latest or at least very recent versions of Firefox, Thunderbird, LibreOffice, and much more, but the GNOME version (44.4 from 2023) is definitely a bit outdated. There’s a ton new utilities written in Rust, and the usual bug and security fixes as well, like for crucial utilities such as OpenSSL and OpenSSH, and things like Python versions 3.14 3.13, 3.12, and 3.9.

A particularly interesting bullet point is maintenance work and improvements for Sun Ray support, and the changelog notes that these little thin clients are still popular among their users. I’m very deep into the world of Sun Rays at the moment, so reading that you can still use them through OpenIndiana is amazingly cool. There’s a Sun Ray metapackage that installs the necessary base components, allowing you to install Sun’s/Oracle’s original Sun Ray Server software on OpenIndiana. Even though MATE is the default desktop for OpenIndiana, the Sun Ray Server software does depend on a few GNOME components, so those will be pulled in.

I’ve definitely put this on my list, once I’m done with my current Sun Ray deep dive on Solaris 10.

If you’re interested in SPARC support, there’s quite a few machines that do work with the SPARC version of OpenIndiana, and recently, there’s been a lot of progress on this front. Running the SPARC version on various servers can work, but desktop use, say, on a Sun Ultra 45, is a bit more problematic due to boot issues and a lack of graphics drivers. The work is ongoing, though, and there’s been a ton of renewed interest.
