In this case it only affected where you put which part of the code, not how
you managed your servers with the tool.
Note that the analogy with programming languages is <how you manage servers>
=~ <how you structure code>, not <how you structure code> =~ <how you
structure code>, what you're trying to put into use here. For judging the
approach, it's irrelevant whether you write a shell script or use somebody's
Ruby plugin to detect mounted filesystems or something like that. It doesn't
change fundamentally how you structure maintenance of your environment.

Of course, starting with their languages' syntax. Though both use the same
underlying ideas, even if they call them differently, and both operate in
similar way. If you know how one works, it's a knowledge that's easy to
transfer to the other.
