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?)
