I finally caught a slow startup (my wife usually has it started by the 
time I get to it) and here's the frontend output:

The above lines come out very quickly, then the hard drive thrashes for 
a long time before the next line comes up and the menu appears on the 
screen.  The difference between the timestamps (20:44:37 to 20:45:25) is 
pretty much the time the hard drive is working (48 secs).

All is normal after that.  Should I increase the verbosity?  Will it 
tell me what's going on during all that hard drive activity? After this 
startup, I exited and re-ran the frontend and it was ready to go in 
about 6 seconds.  Here's that output:

Same output, very different startup time.  What's the difference?
