Running the wait on a healthy, steady-state minion always reported readiness
after a 3s floor:
salt-minion (pid 4114640) ready after 3s
That floor came entirely from the unconditional sleep "$INITIAL_SLEEP" (3s)
before the poll loop. The sleep is vestigial: it predates restart_pending and
never even covered the restart race (see 89e6a746c -- "INITIAL_SLEEP=3 expired
inside that window"). Salt restarts the unit with --no-block and the restart
job is enqueued before service.restart returns, so an in-flight restart is
visible to restart_pending on the first loop iteration; the sleep protects
nothing now.
Drop the INITIAL_SLEEP constant and the pre-loop sleep and start elapsed at 0.
The loop already sleeps at the bottom of each iteration, so the first readiness
check now runs immediately: an already-ready minion returns "ready after 0s",
while the restart path (guarded by restart_pending) and the mid-startup log
gate are unchanged.
