This package provides a replacement for `uname` whose output depends only
|
|
on `stdenv.buildPlatform`, or a configurable `forPlatform`. 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.
