I did upgrade: 128 MB FAST RAM, 64-bit MC68080 @ ~234 MHz with AMMX SIMD instructions, 16 GB industry grade CF and 8 GB microSDHC. OS 3.9 @ 1300 x 768 x 32-bit color HDMI.
"You really want a heavy weight like ZFS (which is a total memory hog, btw., I use it in my server) on Amiga hardware from 1992?"
Yes, I do, because as a Solaris engineer, I understand that ZFS will release memory due to memory pressure from applications, and can in fact run in memory constrained systems. Should be able to run on an Amiga with a Vampire accelerator and 129 MB of RAM. ZIL is auto tuned. Just don't use features like de-duplication and it'll be fine.
(My reboots take about three seconds, with or without the Vampire accelerator, and that's even with OS 3.9.)
Anyways, I know that feeling:

There is even the Amiga reloaded project with a revised A500+ motherboard design coming out, and a new A500-A1200-A4000 hybrid motherboard being designed, so Amiga is far from dead, just very niche.
What hadn't kept pace is the OS: even the most modern AmigaOS 4.1 is far from capabilities of modern operating systems like illumos, and I mean very, very far behind.

You should be happy, that there is such an update to AmigaOS at all !
I understand the enthusiasm. I used an A4000/Cyberstorm060/CyberGfx64 exclusively till 2001. I did not care, that each reboot would take 6 minutes (with starting all the background stuff) and that my system was runtime memory patched into oblivion, and no memory protection in the system. That it crashed 10 times a day (multiply this with boot times, HO HO!). But one day a day has come and one needs to realize: Reality!
