Still reproducible with 0.4.1.  It seems the generated files uid/gid are
causing the discrepancy.  Not sure how that comes to be.  Needs
investigation.  I see nix passes '--frozen' to cargo, but that doesn't
work for us: "Cargo.lock needs to be updated but --frozen was passed to
prevent this".  Not sure if it's key.

To be investigated!

Thanks for the report,

Maxim
