Possibly something like the following pseudocode example? The main point being
to only include a puppet class if there's a certain piece of data in hiera.
node default {
if hiera('usemysql') {
include mysql::service
}
if hiera_array('users') {
include users
}
}
(I haven't tested the above myself. We're still not using hiera at work, more's
the pity.)
