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.
