I recently decided to move it to Void Linux armv7hl, as I wanted to give musl a try
On-topic: Since illumos and its distributions are the only free real Unices (as in: directly derived from SysV) in existence, I admit that I have a soft spot for it. The only problem with it seems to be that every single illumos distribution is tailored for exactly one purpose. SmartOS desktops would not make much sense, neither would OpenIndiana servers, probably. Is there even a way to install OpenIndiana without a GUI?
That said, I really like Tribblix and I can imagine having it as my daily driver soon.
