We can do the same with environment variables.
Let's partition the variables to two categories.
I see what you mean. But it might be not as easy.
One will be the normal variables as we have now. The other we can refer to them as phantom variables; they are never written to persistant storage but live in RAM only. The version variable you refer is one of them.
IMHO it's a more consistent interface.
Well, but how do you present it to the user? Will "printenv" show all variables mixed? So how does the user know which get saved and which not? How do you merge both with the standard CLI and hush in a consistent way? And allthis without (significantly) increasing the memory footprint _and_ keeping the code readable?
As for the state of Linux, we can try to migrate 2.6 to this interface.
Good idea.
