Back when I worked at OmniTI (from like 2015 to 2017), we had an in-house Illumos neé Solaris distro for cloud servers named OmniOS. I didn't use it too much myself as it was somewhat legacy but all the other devs who used it for prod debugging loved all the dtrace/zfs stuffs on it.

LOL, small world. I was at OmniTI from '10-'13; I was around for the transition from Solaris 10 to OmniOS. It was an interesting system and I do wish the rest of the freenix world would learn some of the lessons that could be learned from it. (I guess in fairness they're starting to re: openzfs, ebpf, some of the smarter service management tools, et al.) That was the last time I touched proprietary unix at work, though. Even working at Oracle's AWS competitor later, everything internally was Oracle Enterprise Linux (which is to say, RHEL with the serial numbers filed off).

I wouldn't call that proprietary. It was freely available, and I worked with it for a bit, until switching that project to SmartOS, which is also... not proprietary.

Both were excellent systems to work on in dev and prod.

Pobox also had a few racks of hardware running Illumos/SmartOS as parts of their older stack. it was a pleasure to use once I wrapped my head around it, which was little enough because it was so reliable.

I use OmniOS - its actually not that rare to use if you want a good ZFS server. I am about to do a fresh install on new hardware of it as well. Its not legacy at all.
