tl;dr: Sad to see this, understand the why of it, just not happy about it. Hoping things move forward again and certain things not disappearing
From what I can see of the new GUI (the one in the original post) it looks to me like things are taking a few steps back. I for one actually like, heck loved, the GUI in Corral. I also had the CLI grow on me, fast. This is a sad day for me, and I'm happy I never actually got around to adding shares, dockers and VMs. I'm NOT looking forward to setting everything up again, but it could have been worse I guess. I just hope the new GUI won't be the mess that the old one was, but more like the Corral one, as I actually found it to be intuitive, unlike the old one where I, and a friend of mine I was trying to help, found ourselves wondering "Where the heck did we set that again? Hmm, here? No, there. Ok, but this or that was where?" (I realize some people think differently, but to me and my friend it was a mess.)
Now, I can see where you guys are coming from. Things fell apart and that's a shame, but I hope someone will at least fix the "Error: name 'output_msg' is not defined"-thing... I know, SSH works, but using that when I'm local and have access to both the web-GUI and the physical server makes no sense to me... I will if I have to, but I'd rather have that fixed and stay on Corral until I feel the new/old version is as easy to set up as Corral was, and has full support for everything I'm now used to in Corral... Until that time I guess I'll refrain from setting up anything I'll have to repeat once I do move back to whatever version it is at the time...
I don't think I've seen anything about this in this thread, but I hope you'll continue to use ZFS for the boot pool at least...
Some wonder why some people migrated right away and didn't wait until it was 'stable' and 'tested'. Well, beside the interface making super sense to me, and some people having to use and try new things for things to actually move forward instead of staying old and moldy *chuckles*, my old NAS being toast was a major factor. So basically I had the choice of setting up an old version, and then have to migrate and redo everything again once it was the go-to version (barring something like this happening of course), or simply go with the latest release-version from the get-go.
