The deb and rpm packages never refreshed an installed Service, and the previous package's prerm/%preun uninstalls it unconditionally. When the Service unit existed before the upgrade, the new postinst/%post now reinstalls it with its group and restores disabled, enabled-runtime, masked-runtime and stopped states. First installs and explicit removals never add a Service. rpm runs the new %post before the old %preun. %post records the transaction process (pid and start time) in /run, and /usr/bin/clash-verge-service-uninstall becomes a wrapper that skips only that %preun call and otherwise runs the real uninstaller, now under /usr/lib/clash-verge-rev. deb has no such ordering: an upgrade from a released version still loses the Service, and later deb upgrades reinstall it in place only once the prerm upgrade guard from #8240 ships. The scripts exit 0, because a failing postinst or %post cannot restore the Service. On failure they write /run/clash-verge-service-upgrade instead; package script output never reaches the GUI. At startup the app offers a reinstall if the Service is not ready and warns if its previous state was not restored. Both notices replay when a window subscribes, and the marker is acknowledged only after both are taken. In-app updates stop a Service-run core and hold the core lifecycle until the package manager exits, including after the 30-second startup timeout.
