How to set the starting job id to other than 250

This has to be done with an SQL statement, and should be done after the supervisor installation has been performed.

To start numbering new jobs at 1001, run the following:

mysql -u root -e "INSERT INTO qube.jobid (id,realid,serverid) VALUES(1000,1000,0)"

This can be done on a running supervisor, there's no need to stop it before executing this statement.
