After I've updated to the latest master branch today, I can no longer build rustc,
Compiling rustc_driver fails with no space left error. However, I have plenty of space on my disk, and I can build other rust-projects just fine. Is this a known problem?
Looks like a my local NixOS issue: https://github.com/NixOS/nix/issues/1009. Not sure what exactly exposed it today
