Two questions come to mind:

  1) If you delete those 35 do-nothing scripts,
     what does that do to the boot time?

     (I've often wondered whether it was worth
     putting smarts into rcorder to simply
     skip do-nothing scripts.)

  2) What is syslogd doing for 0.89 seconds?

     I understand why mountcritlocal and fsck might
     take a while, but syslogd doesn't strike me
     as an obvious slow point.  (Unless it's waiting
     on a DNS lookup?  Can that be avoided with
     appropriate /etc/hosts entries?)
