It may be caused by https://github.com/NixOS/nix/issues/1112. For 
example, I have:

error: while setting up the build environment: unable to make filesystem 
‘/run/user/1000/gvfs’ private: Permission denied

These are not completely same errors though, so not sure. I workaround 
it by unmounting this filesystem, but obviously it's a bad idea to do 
this with `/proc`...
