[Nix-dev] Patching uname in stdenv?

[Marc Weber]

> Why they want the kernel version?
Don't ask me. I have't had time to debug it. All I found out was that it
python configured itself to use different modules and some fail.

for older xulunner which got removed there were similar problems.

It looked to me like they are configuring based on target (linux vs darwin ...)

and they all expected linux-2.X with increasing X forever without a major version bump.

Patches for postfix (newer version than current nixpkgs), obsolete xulrunner
and valgrind failed:

POSTFIX failed [1]
xulrunner failed [2]
valgrind failed [3]
