I'm not sure about tagging nodes versus tagging resources like a
class. That all being said, I don't think the right modelling here
is to use tags to determine behavior.
Rather I'd have something like:
class autofs
class autofs::server inherits autofs
class autofs::laptop inherits autofs
and then in the node:
node foo {
include autofs::server
}
That will be more manageable as you aren't relying on what are
essentially magic variables assigned to the node.
Tags are useful for when you want to evaluate just part of the
configuration, etc, such as tagging a class and running just the
security parts, but I wouldn't use them in this way.
