@dimkr Thank you for the new version, I am testing it now.
My first impression is kinda frustration. I have to figure out and change owners and permission. I'm getting it figured out but it will take time.
Edit I got this now. Not so frustrating today. I was up and running with my modified setup scripts is about 20 minutes. And everything works. 
I like the idea of running as spot but it will take some getting use to.
Edit Everything I tested as spot works OOTB except printing. I had to set the root password so I could login to cups.
Here are my observation so far...
When opening a spacefm root window the "run as root" prompt runs off the page. The text path at the top is to long and runs off the screen.
There is no way to tell if i'm in a spot spacefm window or a root one and when I turn on show root indicator color. It's red on black text making it unreadable. I''ll have to look at changing that.
Edit I set the spacefm status bar highlight to red. I'm not sure if this is persistent or not.
The open root terminal window doesn't work when other terminals are open. Not sure if that by default or not in spacefm.
Edit the F4 open terminal here will open as root if you are in a root window.
So far I have not been able to make my custom icons in spacefm work.
Most of the rest of my customization is working.
Edit I got this to work. Must have been something I did because I rebooted and it worked
I'll keep working on it.
Edit
I almost forgot the biggest issue. There are no drives in spacefm even in a root window and all my files are on external drives. I had to open a root terminal and then manually mount sda2. Then I could see it in spacefm.
I did try to add spot to the disk group but this test version has no save folder and I couldn't find a way to log off and on again.
Edit This was just the show internal drives not being checked by default. Devices menu > Settings > Show > Internal drives.
Edit
I did run into another issue shutting down after exiting to the prompt. The only option that worked was startlabwc. I had to use the power button. (quick press did a proper shutdown)
Nope I just did a normal shutdown and it dropped me at the prompt.
Thanks d-pupp
