My first Unix was some PC-based clone, the name of which I cannot remember now, but was also a while before Linux. Not sure whether it was before Xenix or not, though I used Xenix (SCO Xenix at the time, IIRC, or was it SCO Unix) a year or so later.
First Unix's name may have started with E-something. Everex? Not sure.
I think I also got to use Interactive Systems' PC Unix (PC-IX?) around the same time as the first one.
Soon after, moved to Unix on higher Motorola 680x0 processor based minicomputers, and even a multi-CPU SMP RISC Unix (from MIPS) for a while.
Later SVR3 and SVR4. Didn't like 4 though. By then (as I learned later) the UNIX wars had started, and it seemed to be a clunky hybrid of features from the SVR3 and BSD camps. Later worked a good amount on HP-UX too, on their PA-RISC business servers. Liked HP-UX. Pretty stable and powerful OS with a good patch management system and many other features and tools (HP PRM, Glance Plus, Ignite, MC/ServiceGuard, etc.).
The hp-ux mailing list was good too - very friendly and helpful people, I helped out others too.
Never got to work on Solaris, though, which I regret.
I remember I first wrote my selpg utility [1] on a HP-UX box (for a large corp customer, at their request), and then released it on the HP-UX mailing list. Some people appreciated it.
I did Xenix, DG/UX, Aix, got my first Linux distribution in the form of Slackware 2.0.
Tried to get Coherent before, but could not afford it.
Afterwards Red-Hat, Mandrake and SuSE were my favourite ones until I ended up with Ubuntu.
At work I also got to use Solaris and HP-UX.
My first experience with containers was with HP-UX vaults.
However I never managed to leave the worlds of Amiga, Windows and BeOS behind. Specially in terms of Demoscene, IDEs culture, graphics and game coding.
Didn't know about HP-UX vaults. Maybe it came after I stopped using HP-UX, or I just missed it.
Edit: Just googled, it looks like vaults came in either HP-UX 10.24 or 11.x. Think I used HP-UX versions 9.x and upto 10.20.
You're lucky to have worked on Amiga [1]. Read a good amount about it, including its power and performance, multi-tasking, in BYTE etc., earlier, along with the Atari ST, though never got to use either.
(Still remember an Atari ST ad, probably a big deal at the time: "A megabyte of RAM for $x99!"). And where are we now in terms of RAM ...
[1] And had read about Carl Sassenrath, wow. Did all that stuff for the Amiga, and then goes and creates REBOL, maybe single-handedly (?), with the language, and the libs, and the GUI.

Good fun doing a lot of systems stuff on those machines for some years.
