Ok. Now it's /gnu/store/87kif0bpf0anwbsaw0jvg8fyciw4sz67-bash-5.0.16/bin/bash:
nix: command not found. With bash...
I have no idea what's going on here. Guess there are some
nix-interpopability that fails somewhere.
Also: noticed that all associated nix-directories (~/nix-profile, ...)
exist, have root chown, and are not empty. There is even a spotify that I
installed with nix earlier, in ~/.nix-profile/bin. Although I removed nix
from services and packages in my system-wide config.
