Hello Mark,

Thank you for hint, I don't think I have added anyone else
but these:

/etc/group:

guix-builder:x:1002:guix-builder1,guix-builder2,guix-builder3,guix-builder4,guix-builder5,guix-builder6,guix-builder7,guix-builder8,guix-builder9,guix-builder10

And when something is mounted there is no process keeping it
I guess. Thank you, I still need to search for solution.
