A hosts_path pointing to a missing file was silently skipped: the stat task returned exists=false and the guarded block was skipped without a warning, making a typo indistinguishable from "no custom hosts file". The "when: hosts_path is defined" guard already covers the case where the operator does not want a custom file, so a missing path can only mean a mistake. Assert on it instead, and drop the now useless stat.exists guard on the tasks below. Signed-off-by: Florent Carli <florent.carli@rte-france.com>
