–UPDATE–
Via the terminal i update ZimaOs. I hoped that this would solve my problem.
It didn’t.
Results:
the log journal:
–UPDATE–
I have managed to install update 1.52.
In the frontend i see the files, and yes, i got a warning that ZimaOS-HD is full, and that i should migrate.
I can’t migrate cause there is nothing in ZimaOS to migrate from the frontend say’s.
dev/root is 100% full so the problem is still there.
Still investigating.
–update–
Sadly there is no way -at least what i know of- to fix this.
Leaving me with broken ZimaOS.
The only thing left is a full install, that wipe all discs 
Thankfully i made a backup.. .
