Once code can be shared by a second command, putting it in lib makes

If you can come up with a clean way to share the code, go for it.

I note that I have a pending todo item in ls: ls -l /dev/null doesn't

device nodes. If I did one, it's not triggering right...)

I'm leaning against it. If you saw my toybox talk at ELC (it's on  
youtube) I talked about security approaches and containers vs selinux.
