Agreed 100%. All I want to do is move the root filesystem to the SD card and I think this might do it for me, but it has taken me a while to get there...
I have been playing with my Kickstarter Omega2+ for several days now and have yet to get it working to the point where I would consider it usable. I discovered quickly that you can't install much software on it until you expand the memory and have spent these past several days struggling to use an SD card as "expanded memory" without success.
After searching and searching, I finally found the info I wanted and set about formatting and mounting etc only to have the thing slow to an absolute crawl when I started it up a while ago.
I'm afraid I need to re-initialize it yet again and start over.
The Raspberry Pi Zero W can be frustrating at times, but I've always been able to get it up and working and my projects built, programmed and deployed without wanting to hit one with a hammer. For the most part, they "just work". I love the form factor and the expansions but if I can't get it running, it's all just money wasted.
I agree that there ought to be a documented process to fix the biggest weakness of the Omega2+: lack of memory [storage].
