Three host units poll up to 120s for a secret authelia mints on its first
boot, and all three are `Type=oneshot` with no `TimeoutStartSec`. systemd's
`DefaultTimeoutStartSec` is 90s, so it kills them at 90 — before the script
reaches its own `exit 1` and names the file that never appeared.
The wait itself is fine; what's lost is the diagnosis. On a fresh hive the
operator gets a bare start-timeout instead of "authelia has not minted
<path>", several layers from the container that was actually slow.
Found while writing the same unit for Grafana, where the timeout is set —
so this is the existing three catching up with it, not a new pattern.
