`KillMode=process` only signals cf-execd. Any cf-agent spawned by cf-execd keeps running after systemctl stop returns. A mid-run agent can then re-trigger cf-php-fpm (`Wants=cf-postgres`), causing dependencies to be pulled back in after the stop was reported successful. This fix adds `ExecStopPost=` that waits up to 60s for cf-agent to drain, then `SIGKILL`s any survivor. It runs after cf-execd has exited, so no new agents are spawned during the drain. Ticket: ENT-14108 Changelog: cf-execd systemctl stop now waits for in-flight cf-agent to finish Signed-off-by: Lars Erik Wik <[email protected]> (cherry picked from commit cd78895)
