I want to use Augeas to modify "/etc/inittab", but this should only happen when the package "sysvinit" is installed. That package is not under Puppet control (and shall not be).
The "onlyif" from Augeas doesn´t seem capable of checking for anything else than Augeas stuff, i.d. Augeas cannot check if file exists.
Is there a way to achieve this without creating a custom fact?
