Hm, since it's much more likely that updmap-sys fails, I'd rather say
the consumer package is texlive-base-bin, and 'baz' will depend on it,
anyway.

This is more a problem: I think that if the trigger fails and the
package that runs it is put into state failed-config (or even if it's
put into failed-config for non-trigger reasons), this should affect all
packages that Depend on it.
