I tried it, and now things are worse than before.  The startup script
now reads:
        #!/bin/sh
        #
        # Start fetchmail for jonrysh
        
        su - jonrysh -c 'sleep 5; fetchmail'
        
Now there's an additional error in boot.log:
        ...
        Starting atd:                                              [
        OK  ]
        Error opening display!
        fetchmail: open: /home/jonrysh/.fetchmailrc: Permission denied
        
The display did actually start OK after a short delay.  It's a mystery
to me.

Thanks to all - jon
