The wait required both a socket gate and a log gate to pass. The log gate greps the minion log for salt's one-time startup line "Minion is ready to receive requests!", which scrolls out of the log tail on a minion that has not restarted recently. On such a minion the log gate could never pass, so the script ran to its full 120s timeout and exited 1 even though the minion was healthy and connected. This also false-timed-out when salt_minion_service reported a non-restart change (e.g. an enable toggle). The log gate's only remaining purpose is closing the ~2.8s post-connect window where the master sockets are up but _post_master_init() is still loading. Gate it on the current pid's uptime: enforce the ready line only within READY_LINE_WINDOW (90s) of (re)start, and let the already restart-independent socket gate be the steady-state authority past that. The fresh-restart path is unchanged, and if uptime can't be read the strict behavior is kept.
