Hi Steve,
with tags you only can execute classes which are enabled anyway.
It is a way to limit execution on a certain subset of classes.
What else:
you can provide a fact at CLI and react on that specific fact:
FACTER_runnow=true puppet agent —test —tags <class>
Inside your class you will do something like
class foo {
if $::runnow {
notify { ‘Only when run now is set’: }
}
}
