Thank you Felix for the deep answers, at times a bit too deep for me. I am under impression, that I should be fine with this workflow: 1. reconfigure filesystem layout; 2. shut down the system; 3. copy the data to the new physical location; 4. boot the new generation. Is this correct?

I can see a layout where the root partition is mostly dedicated to `/gnu/store` and everything else possible is on other drives. Also, thanks for confirming my fears about BTRFS. In short, I am looking to build the integrity assurance in a structure separate from actual filesystem (was thinking of LVM-like concept). I will take a look at Mdadm.
