Reinstall a Service removed by a previous prerm only when the old prerm uninstalls unconditionally, this dpkg run completed a stop job for it, and its group comes from that same invocation's stdout journal entries. Hand the evidence to the postinst through a single-use file tied to the old version and cleared by every preinst. Refs #8515 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
