Or if you want to put it all in one resource block,
exec { " something _${name}":
command => $some_command_here,
creates => some entry here,
require => $something[$order] ? {
'' => undef,
default => Exec["something_${something[$order]}"]
}
}
That better satisfies my distaste for overrides. In fact, if I didn't want
to use a selector as above then I would use a chain expression instead of a
resource override:
(alternative:)
if something[$order] {
Exec["something_${something[$order]}"] -> Exec["something_${name}"]
}
