download_dev-random hook question

[Christian Storm <christian.storm@siemens.com>]

Hi,

I just stumbled over the download_dev-random multistrap hook:
Why is it that you only create /dev/{,u}random?
Why not also create other essential files like /dev/{null,zero}
as well, e.g., like this:

```
--- a/meta/recipes-devtools/buildchroot/files/download_dev-random
+++ b/meta/recipes-devtools/buildchroot/files/download_dev-random

```
