This package provides a replacement for `uname` whose output depends only
on `stdenv.buildPlatform`. It is meant to be used from within derivations.
Many packages' build processes run `uname` at compile time and embed its
output into the result of the build. Since `uname` calls into the kernel,
and the Nix sandbox currently does not intercept these calls, builds made
on different kernels will produce different results.
