Usage: rebar init [--silent] [--force-new-store]

Initialize (or mount) the ticket store. When a configured remote is reachable,
rebar always mounts an advertised tickets branch and creates a new store only when
that branch is absent. If the remote cannot be reached, initialization fails closed
to avoid splitting ticket history.

  --silent             Suppress successful initialization messages.
  --force-new-store    Explicitly create a new store only when the configured remote
                       cannot be reached. Has no effect for a reachable remote.
