Description

When the server is in recovery but waiting for the first client to connect, it would be useful to print a message on the console every 10 minutes or so, in case the admins are waiting for recovery to complete. This has been reported a few times in the past, and it isn't obvious that recovery will not start until the first client connects.

It would also be useful to print something similar in the recovery_status file in /proc.
