    im not sure i understood this comment.
    i think you're trying to say that `plugin` can't be None here since the 
test for enabled has already been performed earlier?
    the first line of the comment makes it sound like `plugin` can be None when 
it cant

> The execution plugin serves as the default plugin, i.e. if no other plugin 
> was specified, it'll be used to execute scripts in operations.
> These scripts will currently only execute locally. The execution plugin also 
> supports running scripts on remote machines (via SSH).
> One option is to have the parser recognize whether the node in question is 
> contained inside a host node, in which case the script should be executed 
> remotely (by default, yet overridable by specifying the full plugin operation 
> mapping), and if not then it should be executed locally.
> Another option is to have the user specify it using special syntax, e.g.:
> "local > script.sh" and "remote > script.sh"
