Hi Norman,

Thanks for your quick and clear response.

I wonder why the manager did start my vm-nixos when part_blk became 
available but decided to kill it when the inspector closes. It knows 
there is a dependency.

Bummer, I had in mind to dedicate that secondary partition to the 
vm-nixos with a policy and leave the rest to Sculpt.

But first, I'll give your suggestion a try. I'll probably learn a lot again.

(Or I'll give the whole disks to the VM, that's what I want in my 
desktop environment, eventually. ZFS loves whole disks.)

Cheers, Guido.
