nixpkgs/pkgs/build-support/kernel/modules-closure.nix
Eelco Dolstra 16da00e64d * Doh! Since r15200, modules-closure.sh generated an empty set of
modules for the initial ramdisk if there were no additional kernel
  module packages (such as the NVIDIA driver or AUFS), leading to a
  kernel panic in the initrd.  This was because in that case modprobe
  would print paths referring to the kernel path rather than the
  module aggregation path, and then `sed "s^$kernel^$out^"' would
  silently fail.  Fixed.

* Also, use depmod here rather than doing sed hackery on modules.dep.

* Also, `allowMissing' was broken (missing "$" before the variable
  name).
