As near as I can tell, these charts mean my system is
just sitting there like a lump for the first 18
seconds doing absolutely nothing (with or without the
USB drive I thought it might be waiting to spin up).

Lots of the sample charts on the www.bootchart.org
web site don't have these big empty gaps up front.
I'm jealous :-).


I don't know why your nash sleeps for so long.. it's most likely a bug.
Meanwhile, you have 3 other big sleeps:
* ifup-eth (network card acquiring info from DHCP)
* ntpdate (time sync with network)
* S99local/sleep (not sure what that is)

If you get rid of these, you'll shave off ~12 seconds from your boot time ;)
