It's not actually that bad. I tend to create a whole class just for the
update commands and set a global resource default require as Daniel has
shown.
Another option is to create your own defined type, say "apt_package" that
takes into account the local customizations at your site that wraps a normal
package type with all the right dependencies.
I'm finding this is more flexible, simply because you can set the
require/before however you like on individual resources without having to
worry about overriding the global resource default, or know what it is.
