This question was asked nearly 6 years ago, and remains a relevant question. However - the accepted answer is no longer relevant because rc.local has been deprecated.

There are (at least) two alternatives to rc.local that - as of this date - are valid and supported:

1. systemd

2. cron

In comparison, cron is simpler, systemd is more precise. In general, either one will work for most requirements.
